Is there a fix for this or do I just have to disable vitalization in the UEFI?

Hello romulasry,

romulasry <romulasry <at> protonmail.com> skribis:

I don’t actually see a crash on this picture, just repeated messages
like:

  AMD-Vi: Event logged [IO_PAGE_FAULT …]

Did the system actually crash or hang?

I suppose it would be worth reporting the issue to the kernel developers
because that doesn’t seem to be Guix-specific.

Thanks,
Ludo’.

I get the same hang when I turn off amd virtualization.

It must be the bottom error that is causing it. I assume because i get the same error then hang when it is the IOMMU setting is set to off in the UEFI.

It is a amdgpu firmware bug, will guixsd ever support it?

Romulasry,

We've had some trouble booting with the non-free AMDGPU graphics 
cards before, but the ‘AMD-Vi IOMMU’ part is new to me.  What 
exactly happens?  Which error messages (if any) do you get 
(pictures are fine, but please compress them to a few 100k or host 
them elsewhere)?

> will guixsd ever support it?

We can certainly try, if we know what (kernel CONFIG_ option, 
kernel command-line option, …) is required.

Since you seem to know more about the bug, could you explain it in 
more detail of provide a link to more information?

Thanks,

T G-R
