wonder of wonders, miracle of miracles :)

panic: Assertion td->td_flags & TDF_SINTR failed at
/usr/src/sys/kern/subr_sleepqueue.c:761 at line 761 in file
/usr/src/sys/kern/subr_sleepqueue.c cpuid = 0;
Debugger("panic")

Is that related to this kernel patch (pasted at bottom) I've seen cross
the list today?  If so, has this patch been committed to the cvs sources,
or will i need to apply it manually?  if not, what might my next step be?
