Crash after updating kernel/world to 13.1-RELEASE-p5

This is after updating my kernel and world to 13.1-RELEASE-p5.  I grant you the
backtrace here sure points to the openzfs code, but why does the crash happen
only with graphics/drm-510-kmod installed and amdgpu.ko loaded, but not
otherwise?  For the time being, I will be running WITHOUT amdgpu.ko in my
kld_list, and I am confident this crash will not occur.

I got maybe six boots with kern.smp.disabled=1 with no crashes on
13.1-RELEASE-p2.  But based on an earlier comment I updated to 13.1-RELEASE-p5.
 Then after going back to kern.smp.disabled=0 I got another of the crash.

I did observe that something in sys/contrib/openzfs/module/zfs got updated
between p2 and p5, but it doesn't seem to have fixed this crash.

Compiling graphics/drm-510-kmod under p5 yielded an amdgpu.ko that was
identical to amdgpu.ko compiled under p2.
