Hi

In Debian we got a regression report booting on a Lenovo IdeaPad 1
15ADA7 dropping finally into the initramfs shell after updating from
6.12.30 to 6.12.32 with messages before dropping into the intiramfs
shell:

mmc1: mmc_select_hs400 failed, error -110
mmc1: error -110 whilst initialising MMC card

The original report is at https://bugs.debian.org/1107979 and the
reporter tested as well kernel up to 6.15.3 which still fails to boot.

Another similar report landed with after the same version update as
https://bugs.debian.org/1107979 .

I only see three commits touching drivers/mmc between
6.12.30..6.12.32:

28306c58daf8 ("mmc: sdhci: Disable SD card clock before changing parameters")
38828e0dc771 ("mmc: dw_mmc: add exynos7870 DW MMC support")
67bb2175095e ("mmc: host: Wait for Vdd to settle on card power off")

I have found a potential similar issue reported in ArchLinux at
https://bbs.archlinux.org/viewtopic.php?id=306024

I have asked if we can get more information out of the boot, but maybe
this regression report already rings bell for you?

Jonathan reported a similar failure regarding to hs400 on RK3399
platform.

Maybe you could try to revert :
28306c58daf8 ("mmc: sdhci: Disable SD card clock before changing
parameters")

#regzbot introduced v6.12.30..v6.12.32

*sigh* apologies for the "mess", the actual right report is https://bugs.debian.org/1108065 (where #1107979 at least has
similarities or might have the same root cause).
