Hi there,

I just tried to prepare my new laptop for UFEI+secureboot by creating a single unified kernel image including kernel,initrd,microcode,etc.
NB: The partition layout has a vfat/Efi partition and a luks encrypted lvm container holding SYS(Root), Data(home) and swap.

I added uki and ukify use flags to installkernel and systemd, checked the configuration again and configured the kernel by emerge --config sys-kernel/ gentoo-kernel.

Bulding the kernel image seems to work fine, the log messages say its creating a initrd using dracut, creating a efi file, signing it properly and even installs it under /boot/efi/EFI/Linux.

When booting it, it loads the kernel and then seems to get stuck:

Timed out waiting for device /dev/gpt-auto-root
Dependency failed for File System Check in /dev/gpt-auto-root
Dependency failed for Root Partition
Dependency failed for Initrd Root File System
Dependency failed for Initrd Mountpoints Configured in the Real Root
Dependency failed for Initrd Root Device

Then it ends up in an emergency shell.

There's a log in /run/initramfs/rdsosreport.txt, which reveals that it does
not find my encrypted lvm partition (LUKS encrypted lvm container holding SYS, DATA, SWAP, etc), which obviously needs to be setup first. Seems like some boot parameter is missing.

Checking systemd's USE flags: Relevant flags lvm + cryptsetup + boot + secureboot use flags are set

To me it looks like as if its missing information which partition to use for decrypting/mounting, and which lvm volume to use as real-root.

Is this a dracut configuration? A systemd configruation? An installkernel configuration? Something else?

Thanks
Alex

I'm not the right person to comment reliably on this, because I don't use systemd and do not use LVM, but until someone else chimes in I'll give it a go ... :-)

Why is the ESP mounted under /boot/efi, instead of /efi?

The gpt-auto-root is a script which tries to automatically detect and mount
the root fs. Did you create your partition(s) with GPT and did you select the correct partition type "Linux Root (x86-64)" to make sure the partition GUID code for LUKS is correct according to the Discoverable Partitions Specification? If you used fdisk, you'll probably need to add the partition type GUID code manually, as advised in the Handbook. Press -i in fdisk to
find out what it currently is set as.

Then it ends up in an emergency shell.

Did you configure dracut to include the necessary modules and to add the corresponding LUKS and LVM UUIDs?

I think this is a dracut configuration issue, because systemd's 'kernel- install' setup is relatively straight forward:

https://wiki.gentoo.org/wiki/Installkernel#Systemd_kernel-install_.28USE.3D. 2Bsystemd.29

If the problem is with dracut as I suspect, you may find 'sys-kernel/ugrd' easier than dracut for your type of installation, but dracut should work too
if correctly configured.

HTH.

Dunno which update tool it is, but istr there is a tool that does
exactly that ...

It turns out I actually had the old file in /etc/config-archive all
along. It's a shame dispatch-conf and friends don't do an automatic
3-way merge. This would make things so much simpler and less stressful.

Until it gets it wrong. Which is exactly why it doesn't. Which is why

Initially, this delay to POST would happen randomly and rarely. Now it happens every time.

Things I tried:

1. Reflashing the UEFI firmware - it didn't work because it already has the
latest firmware.

2. Removing the main battery and holding down the power button for 15 seconds, hoping to reset the firmware.

3. Leaving the PSU cable connected overnight.

4. Testing the RAM and HDD.

None of the above improved the situation, or indicated what might be wrong.

I'll reseat the RAM sticks and the HDD next, in case a contact is oxidised,
but what else could cause this noticeable delay to POST? A failing RTC CMOS battery?

We have had a few of these at work and these symptoms were cured by a
new CMOS battery. The voltage on the battery has likely dipped to
2.9-3.0 volts; they get unreliable then (i.e. it's dead.) If you leave
it long enough you'll start getting RTC errors on POST.

I'd try that first, assuming you can still get the CMOS battery for these.

Dan

Thanks Dan, will do. I was planning to take it apart soon to replace the
HDD with an SSD, so this would be the first thing to check. I expect
finding a replacement unit will be difficult. Every Lenovo RTC battery
seems to have a different part number.

Some things are worth waiting for, others no so much. :-(

So, this laptop was taking longer and longer and longer to boot, until it eventually stopped booting 3-4 months ago:

When the power button is pressed the cooling fan spins for a second or two, then it stops. A few minutes later the CPU overheats and eventually it goes into a thermal shutdown. Using an external fan to push air through merely delays this process, but the laptop still does not boot. I am getting a black screen and no POST for many minutes until it cuts out.

I tried to reset the MoBo BIOS by pressing the power button with no battery or mains connected. I also removed the newly replaced CMOS/RTC battery and pressed the power button, but the same failure mode remains after I
reassembled everything.

Do I have:

1. Corrupted MoBo UEFI firmware?
2. A dying/dead chipset?
3. Something else?

Is there anything else I could possibly try?

usually in laptops which become dirty (they all do, and it's very difficult to take them apart and clean and reassemble) the hard drive is the first thing to fail completely.  A dying hard drive can easily slow/halt boot. 

CPU/GPU are likely next along with the power supplies for those chips.  All you can really do is take it apart, clean it, and if possible test the hard drive etc. in a known good machine.  Alternately, try a different hard drive (either a replacement
or a small, cheap used one for testing).  Check that all the fans still spin freely after cleaning them, if possible test them on a power supply (note that some will be 5V and some 12V, be careful to read the labels or start low). 

The CPU/GPU may or may not have become marginal, same goes for the memory and all the other chips and other temperature sensitive parts.  Really, it's essential to fix a laptop soon after it starts acting up, those higher temperatures age everything
rapidly and make all the parts more likely to fail.  You may or may not be able to get that laptop working again.

If you can get it basically working test the hell out of everything with utilities like stress so it doesn't fool you and die hard soon.

I hate working on laptops and AIO desktops, always hard to take them apart and put them back together and they both need regular cleaning, before they act up (or at least immediately when they start acting up).  Because of the dust I clean my desktops
at least once a year, also a pain but much easier than a laptop or AIO.  This keeps them from wearing out as quickly and as some one on a small fixed income that's very important to me.

Depending on your' situation and what your' time is worth replacement might be the way to go, though you still probably want to recover what you can from the drive.

The hard drive is good.

CPU/GPU are likely next along with the power supplies for those chips. All you can really do is take it apart, clean it, and if possible test the hard drive etc. in a known good machine. Alternately, try a different hard
drive (either a replacement or a small, cheap used one for testing).

The laptop has been used on a cooling pad away from dusty surfaces and cleaned regularly. When I took it apart there was just a little dust on the fan and exhaust, because it hadn't been cleaned for ~6 months or so.

The drive is in good health according to smartctl and fully accessible over a USB cradle.

Check
that all the fans still spin freely after cleaning them, if possible test them on a power supply (note that some will be 5V and some 12V, be careful
to read the labels or start low).

The fan spins freely when rotated by hand. It also spins initially when the power button is pressed. However, it stops within a couple of seconds and
does not start again.

This makes me think ... normally when the fan starts spinning at boot it soon climbs up to maximum speed while the BIOS runs through POST. Then it slows down as the BIOS hands over to the OS. Its connected to the MoBo via 4 wires which control its PWM. The wires are in a good condition, but I have no way
to check what its miniature socket voltage could be while I power it up starts without some spare fan or plug. Anyway, I don't know if some pull-up resistor in the fan control circuit is damaged, but even if it failed wouldn't the fan continue spinning but at a low speed? This one stops dead. Hence it makes me think of a corrupt/damaged MoBo chipset or firmware. :-/

I hate working on laptops and AIO desktops, always hard to take them apart and put them back together and they both need regular cleaning, before they act up (or at least immediately when they start acting up).

Yes, I *really* don't like laptops for a number of reasons, no matter the convenience they offer. The inherent difficulty in cleaning/upgrade/repairs, added to their relatively small screen size, makes me wanting to avoid them.

Because of the
dust I clean my desktops at least once a year, also a pain but much easier than a laptop or AIO. This keeps them from wearing out as quickly and as some one on a small fixed income that's very important to me.

The design compromises on a laptop compared to a desktop are many. I don't think I ever had a laptop lasting for more than 6 years of continuous usage without things breaking, no matter how careful I was with it. By the time its battery needs replacement something around the corner is usually about to fail on me.

I recall seeing the same symptom on an HP laptop some years ago now. I replaced its fan, but it continued to fail to boot in the same manner. I
never got to the bottom of it at the time.
