Dear Maintainer,
The system will log an error, followed by 100% cpu usage on one core, I believe by the kernel, which results in the message
```
[drm:dc_add_plane_to_context [amdgpu]] *ERROR* Head pipe not found for stream_state 00000000b7629c18 !
```
logged endlessly and as fast as the CPU can process to the kernel log.
The trigger for this issue is unclear to me, as it will not happen on every boot of the system, and can take hours, days or
weeks to appear after a reboot.
Other system functions appear to work as normal, or not degreded in a way I have noticed, as long as the logs are rotated.
Rebooting the system is my current approach when this error happens, and buys time until it occurs again. This system has run
without issue for >60 days on an affected kernel version, so I suspect there is no guarantee this bug will always appear.
The system is run as a mostly headless server, does not hibernate, sleep or suspend. It *is* connected to a TV via a HDMI cable,
that turns on and off throughout the day, and is one of the few inputs relevant to the amd gpu driver that I suspect could be a
trigger. This is connected to the motherboard HDMI connection, using the iGPU of a Ryzen 2200G
This system is running openmediavault (intalled from that install media), but I am logging here as I suspect it does not make
modifications to the kernel and core debian system.
The last time this was known to be stable for me was on the 5.10 kernels under bullseye, and on both bullseye and bookworm under
the 6.x kernel this issue has appeared.
I have captured two instances of this from separate dates included below. The last line is the one to repeat infinitely from
this point onwards. It is difficult to capture as the logs will quickly either fill up the hard drive, or get log rotated
out, which means that it has been hard to observe anything other than the final message in the logs! It has been recurring
around 6-10 times total in a 12 month period.
Please note that the last kernel log included by `reportbug` is on a fresh reboot of the system where this issue has not
occured yet and may be of no use - else it would only capture the spammed message log!
Logs from first time I caught the issue:
