Hi, Thorsten here, the Linux kernel's regression tracker.
I noticed a report about a regression in bugzilla.kernel.org apparently
related to the bluetooth code. As many (most?) kernel developers don't
keep an eye on the bug tracker, I decided to write this mail. To quote
from https://bugzilla.kernel.org/show_bug.cgi?id=219294 :
> Since Kernel 6.11 compiled from vanilla source, I get occasionnaly an Oops at boot on my Lenovo Slim 5.
> This is a regression.

See the ticket for more details and another oops. Reporter is CCed.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

Everything you wanna know about Linux kernel regression tracking:

If I did something stupid, please tell me, as explained on that page.
P.S.: let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:

I suspect this has been fixed recently:
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=6f3f7e9414834fc4210a2d11ff6172031e98d9ff
@Chris Lu perhaps you want to check since it seem to be hitting
something else related to btmtk code:
Sep 17 21:53:23 latile kernel: Bluetooth: hci0: Execution of wmt
command timed out
Sep 17 21:53:23 latile kernel: Bluetooth: hci0: Failed to send wmt

From the log, I think this issue is less likely related to the changes
I submitted few days ago. Instead, I believe this issue is caused by
following patch
https://lore.kernel.org/all/3c3dfe8efc70af04794035537c7c40a52f2266d5.1715109394.git.sean.wang@kernel.org/
which MediaTek also found the problem after applying it. This patch
would occasionally cause setup failed on specific platform +
MT7921.(This patch was accepted between v6.10 to v6.11.)
In Auqust, Our member Hao submitted another change to fix it which
hasn't been accepted yet. Hao's change is necessary. He has verified
this patch is workable.
https://lore.kernel.org/all/20240822052310.25220-1-hao.qin@mediatek.com/
Could you help to review it? Please tell us if MediaTek has to resend
or rebase this change again.
Thanks a lot!
