Also, scsi_scsi_cmd() looks like it's been exiting without a biodone() on
an attached buffer in a number of error cases, leading to locked buffers.
update got lost. This is responsible for ensuring that dirty mmap() pages
get periodically written to disk. Without it, long time mmap's might not
have their dirty pages written out at all of the system crashes or isn't
cleanly shut down. This could be nasty if you've got a long-running
writing via mmap(), dirty pages used to get written to disk within 30
seconds or so.

kernal page table may need to be extended. But while growing the
kernel page table (pmap_growkernel()), newly allocated kernel page
table pages are entered into every process' page directory. For
proc0, the page directory is not allocated yet, and results in a
page fault. Eventually, the machine panics with "lockmgr: not
holding exclusive lock".
