Subject: Regression on linux-next (next-20240506)
Hello Thomas,
Hope you are doing well.
This mail is regarding a regression we are seeing in our CI runs[1] on linux-
next repository.
Since the version next-20240506 [2], we are seeing the following regression
`````````````````````````````````````````````````````````````````````````````````
Starting dynamic subtest: gt_contexts

Details log can be found in [3].
After bisecting the tree, the following patch [4] seems to be the first "bad"
commit
`````````````````````````````````````````````````````````````````````````````````````````````````````````
2fd001cd36005846caa6456fff1008c6f5bae9d4 is the first bad commit commit

arch: Rename fbdev header and source files
`````````````````````````````````````````````````````````````````````````````````````````````````````````
We also verified that if we revert the patch the issue is not seen.
Could you please check why the patch causes this regression and provide a fix
if necessary?

Gentle Reminder 😊
Sorry, I didn't notice the report before. The commit is not related to
ACPI. There's now asm/video.h and acpi/video.h. Maybe there's a conflict
among included files.
Do you have a kernel config to build with?
Best regards
Thomas
Thank you.
Regards
Chaitanya
