Details

Description:

Starting with kernel version 6.4.9, the tpm_crb module fails to initialise on my machine, which unfortunately causes my LUKS drives to not unlock. It previously worked without issue on earlier kernel versions. The kernel error message is 'tpm_crb: probe of msft0101:00 failed with error 378'.

Note that I am using the linux-zen package over linux, but I would be surprised if the patches applied for the zen kernels would cause this issue. For that reason and because it is a bit of a pain, I have not tried the vanilla kernel at version 6.4.9 or 6.4.10, although if it would be considered helpful I could.

Additional info:
* Package versions: linux-zen-6.4.9.zen1-1, linux-zen-6.4.10.zen1-1, and linux-zen-6.4.10.zen2-1
* Motherboard: MSI Pro B660M-A

Steps to reproduce:

The issue is likely contingent on your hardware, but provided you have the same or similar hardware, boot with kernel version 6.4.9 or greater and observe that the tpm_crb module fails to initialise.
This task depends upon

> I have not tried the vanilla kernel

Why not? It's a *must* if you're troubleshooting. Especially when looking at the recent commits to linux-zen...

Either way, it sounds like an upstream kernel regression. General advice for debugging kernel regressions [1]. git bisect is the way. Identifying the offending commit is highly desirable if you have to report it upstream. Please let us know what you find out.

I have exactly the same issue with linux-6.4.11 and linux-6.4.10 works without problem.

I posted already in [1], but just stopping by to say that I applied Mario's patch to 6.4.11-arch1-1 and it fixed my issue.

Just saw the edit:

Tried linux-6.4.11-arch2-1 from core-testing and it also works.
