I have an AMD Radeon RX 480 graphics card.
A few months ago there was this AMD firmware bug that was affecting amdgpu users.
This bug has since been resolved, and everything was fine for a while.
However since recently my workstation sometimes gets stuck on boot due to what seems to be an amdgpu-related error.
I need to mostly hard-reset it multiple times until I get lucky and the error for once does not happen, and then everything seems to work.
I see the error lines show up on boot, and sometimes, if i'm very quick, Ctrl+Alt+Del still works for a clean reboot before the workstation freezes.
The bug has already been observed by user utter86.
Its signature error log lines seem to be,
[ 18.508419] workstation kernel: [drm:amdgpu_vce_ring_test_ib [amdgpu]] *ERROR* amdgpu: IB test timed out.
[ 18.508517] workstation kernel: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* amdgpu: failed testing IB on ring 12 (-110).

I get these error messages but they seem a bit random, some boots they're there, some boots not. They don't seem to cause any problems here, boot always succeeds, X, games, video etc. work fine.
One thing that gets rid of them (for me) is iommu=soft on the kernel command line, so you could try that.

Sorry, ignore that, iommu=soft doesn't get rid of them. Others have these errors too: https://bugs.freedesktop.org/show_bug.cgi?id=97362 for example.
