Hi,
I moved to 12-Current after my systems kept freezing with 11.1-Release
and -Stable. Basically it seemed to only affect two of the machines
that I upgraded recently to 11.1-Release branch. These are embedded
Intel J1900 motherboards from SuperMicro.
Currently on 12-Current they seem to be doing really well like with the
previous 10.x-Release. Though I am seeing a kernel stack trace:
lock order reversal:
1st 0xfffff80106be25f0 zfs (zfs) @ /usr/src/sys/kern/vfs_mount.c:849
2nd 0xfffff80106c53068 devfs (devfs) @
/usr/src/sys/kern/vfs_subr.c:2606
stack backtrace:

Should I be alarmed about this?
