I had system hangs, until 1.23.2.3 of kern_lock.c was committed.
Since then, I've had what appeared to be a hang that became a panic
after waiting 19 minutes. See PR 11993 (panic: getnewbuf:
inconsistent EMPTY queue, qindex=0). This has only occurred once,
on June 2.
Before anyone can debug this we will need some additional
information like a description of you hardware, uname -a output,
dmesg output, a copy of your kernel config file, and a bactrace
listing from your vmcore dump. Once you have the required
information, the best way to report bugs of this kind is through
send-pr(1). You may still wish to post to this list to provide the
rest of us with some kind of heads-up notification and maybe flush
out comments about similar experiences into the open.
Best of luck.
