Recent kernels resulted in a blank screen, with Xorg.0.log reporting:
(II) [KMS] drm report modesetting isn't supported.
Sometimes while bisecting the pc came to a complete lockup (magic Sysreq
unresponsive).
At the end of bisecting I had:

drm/radeon: remove load callback from kms_driver
The ".load" callback in "struct drm_driver" is deprecated. In order to remove
the callback, we have to manually call "radeon_driver_load_kms" instead.
This machine reports having:
AMD A10-6800K APU with Radeon HD Graphics
with the gpu appearing as
Advanced Micro Devices [AMD/ATI] Richland [Radeon HD 8670D] 1002:990c

Using current Linus git head kernel, I was able to save the dmesg output: [ 17.218724] [drm] radeon kernel modesetting enabled.

Follow-up, qla2xxx appears to be fixed, most recent test was with:
commit 684a64bf32b6e488004e0ad7f0d7e922798f65b6 (HEAD -> master,
origin/master, origin/HEAD)
Merge: f7fccaa77271 68898131d2df
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date: Tue Sep 24 15:44:18 2024 -0700
Merge tag 'nfs-for-6.12-1' of
git://git.linux-nfs.org/projects/anna/linux-nfs
I suppose the most likely fix was probably this one but I do not have
the HW to verify
(report I got was on an AMD EPYC 7262):
