Hi Ard

I tested 6.1-rc2 but the issue isn’t fixed yet.

I guess you had applied the patch in the link below to fix the issue right?

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/firmware/efi?h=v6.1-rc2&id=8a254d90a77580244ec57e82bca7eb65656cc167

Here is the build log of the kernel I compiled, just in case you need :-

https://github.com/t2linux/T2-Ubuntu-Kernel/actions/runs/3319113145/jobs/5483863180

Although if I apply the patch you sent me on 6.1-rc2, the issue gets fixed again.
