re: kern/57059: amdgpu graphics ring test failing

[matthew green <mrg%eterna.com.au@localhost>]

this is probably a bug in the teardown that netbsd triggers
that linux doesn't do (cv destroy), but that bug is only
revealed by the the ring test failed, which is very like the
issue in PR#56714.

if you're currently booting from UEFI, can you try switching
to BIOS boot and see if the accel proilem goes away (and with
it, the cv destroy problem.)
