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: #0 0xffffffff80ac52d3 at witness_debugger+0x73 #1 0xffffffff80ac5152 at witness_checkorder+0xe02 #2 0xffffffff80a392fe at lockmgr_lock_fast_path+0x1ae #3 0xffffffff8106a060 at VOP_LOCK1_APV+0xe0 #4 0xffffffff80b3df56 at _vn_lock+0x66 #5 0xffffffff80b2cac2 at vget+0x82 #6 0xffffffff809325bd at devfs_allocv+0xcd #7 0xffffffff809320c3 at devfs_root+0x43 #8 0xffffffff80b234cc at vfs_donmount+0x11ec #9 0xffffffff80b222b2 at sys_nmount+0x72 #10 0xffffffff80eee83b at amd64_syscall+0x79b #11 0xffffffff80eccebb at Xfast_syscall+0xfb Should I be alarmed about this?
