Hi, Thorsten here, the Linux kernel's regression tracker.
James, Jarkoo, I noticed a report about a regression in
bugzilla.kernel.org that appears to be caused by this change of yours:
6519fea6fd372b ("tpm: add hmac checks to tpm2_pcr_extend()") [v6.10-rc1]
As many (most?) kernel developers don't keep an eye on the bug tracker,
I decided to forward it by mail. To quote from
https://bugzilla.kernel.org/show_bug.cgi?id=219229 :
> When secureboot is enabled,
> the kernel boot time is ~20 seconds after 6.10 kernel.
> it's ~7 seconds on 6.8 kernel version.
>
> When secureboot is disabled,
> the boot time is ~7 seconds too.
>
> Reproduced on both AMD and Intel platform on ThinkPad X1 and T14.
>
> It probably caused autologin failure and micmute led not loaded on AMD platform.
It was later bisected to the change mentioned above. See the ticket for
more details.
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.
[1] because bugzilla.kernel.org tells users upon registration their
"email address will never be displayed to logged out users"
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:
