 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.)
