Black screen during boot

[Azfar]

Stuck at black screen during boot, sometime after GRUB choice/during the process load (lots of OK text).

Successfully boot into recovery, then reverted packages updated during the problematic date, by referring to https://www.cyberciti.biz/howto/debian-linux/ubuntu-linux-rollback-an-apt-get-upgrade/ and https://askubuntu.com/questions/138284/how-to-downgrade-a-package-via-apt-get

At first, there's around 6 packages in all then managed to pinpoint the root cause to the linux-firmware package. Due to the hardware becoming very hot, even when nothing is running (well it is stuck during boot) then I guess it must somewhat be related to the processor or ACPI as the fan also runs very loud.

Downgraded linux-firmware:amd64 20230323.gitbcdcfbcf-0ubuntu1.5 to 20230323.gitbcdcfbcf-0ubuntu1.2 and system can boot properly again.

Attached is the latest boot log. One of the problematic boot is shown in log at time Aug 08 18:45:53 and the working (after downgrade package) is on Tue Aug 08 22:03:21.

Can you try the following?

1) Install linux-firmware 20230323.gitbcdcfbcf-0ubuntu1.5
2) Backup /lib/firmware/amdgpu/yellow_carp_dmcub.bin
   $ cp /lib/firmware/amdgpu/yellow_carp_dmcub.bin /lib/firmware/amdgpu/yellow_carp_dmcub.bin.orig
3) Download latest from kernel.org:
   $ wget -O yellow_carp_dmcub.bin https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/amdgpu/yellow_carp_dmcub.bin?id=253cc179d849fc82489773b2b553a49858d8725f
4) Copy latest:
   $ cp yellow_carp_dmcub.bin /lib/firmware/amdgpu
5) Update initrd:
   $ update-initramfs -u -k $(uname -r)
6) Reboot

Does that fix the problem with linux-firmware 20230323.gitbcdcfbcf-0ubuntu1.5?

[Azfar (matdjon)]

Yep the linux-firmware 20230323.gitbcdcfbcf-0ubuntu1.5 works now after following steps as in #5.

Thanks for the easy to understand instructions.

Can you please provide output from this script?
https://gitlab.freedesktop.org/drm/amd/-/blob/master/scripts/psr.py

[Azfar (matdjon)]

There's a bug in the python script.

DRI device 0 DMCUB F/W version: 0x0400003e
Traceback (most recent call last):
  File "/home/farr/Downloads/psr.py", line 81, in <module>
    decode_psr_support(f)
  File "/home/farr/Downloads/psr.py", line 20, in decode_psr_support
    print("○ %s [%d]" % (PSR_SUPPORT[v], v))
                         ~~~~~~~~~~~^^^
KeyError: 0

I don't really know much python. I commented the line and added as the PSR_SUPPORT[v] is error, and added new line print("o [%d]" % v).

Output is:
DRI device 0 DMCUB F/W version: 0x0400003e
o [0]

[Mario Limonciello (superm1)]

Thanks. That's a different than the panels tested on my side when I verified the SRU and you appear not to have PSR enabled which is different than what I validated (all my panels support it)

I've marked this as duplicate of the other in progress SRU for the updated firmware that helped you.
