Hello. Kernel 6.11.0 crashes. 6.10.0 builds. Al Viro and Dr. David
Alan Gilbert have been helpful, and asked that I
post a git bisect log. The last log step seems odd, but the second last
step "Remove useless function call" might be what broke.
My hardware is old corei7 quad core/8 thread Tylersberg/Nehalem with an
AMD RX 6500XT. That's the odd combination.
Thanks in advance,
Bob

Thank you for doing this!
My reading is that's fine, I think the next one:
tree: git bisect bad
[a171cce57792b0a6206d532050179a381ad74f8f] drm/amd/display: Check and log for

or the one after it is the culprit?
Adding the two Alex's from AMD back onto the thread.

The commit triggers debugger in case of in case of errors.
Is the config CONFIG_DEBUG_KERNEL_DC (Enable kgdb break in DC) enabled
in .config, i.e. can you check "grep CONFIG_DEBUG_KERNEL_DC .config"?
If so, can you also try to disable it and check whether you can see
error messages "Failed to execute VBIOS command table" in kernel log?

I will set it to # CONFIG_DEBUG_KERNEL_DC is not set
also,

Hopefully this helps. Please mail me if you for more information. I
have changed my .config and set
# CONFIG_DEBUG_KERNEL_DC is not set
I am attempting to build 6.11.0.

Hi Bob,
It seems the below change in a171cce57792 causes the hang when
CONFIG_DEBUG_KERNEL_DC is set.

If you can help confirm thefollowing fix the hang, I will prepare a
revert patch next week:
* Set CONFIG_DEBUG_KERNEL_DC and revert the above change, i.e.

So the final change:
CONFIG_DEBUG_KERNEL_DC=y
(about line 227) of drivers/gpu/drm/amd/display/dc/bios/command_table2.c
BIOS_CMD_TABLE_REVISION(dig1transmittercontrol, frev, crev);
with the 6.11.0 kernel,
and the X server is working OK.
Thanks,
Bob

There is a fix in amd-staging-drm-next:

ASICs

@@ -227,7 +227,7 @@ static void init_transmitter_control(struct
bios_parser *bp)

It should land in 6.12. See
