 The machine crashed again. This time it hit an assertion but not the
 one recently added. Here is the backtrace. It looks like it ran out
 of kva and tried to sleep from interrupt context.
 
 panic: kernel diagnostic assertion "(l->l_pflag & LP_INTR) == 0 ||
 panicstr != N ULL" failed: file "/usr/src/sys/kern/kern_condvar.c",
