Can you try > http://people.freebsd.org/~jeff/sched_ule.c? I have made some changes > that may fix this. cvsuped today at 17:23 UTC and replaced sched_ule.c afterwards. The almost-instant panics are gone. Also, the oddity I reported about ULE/BOINC on this list earlier has been fixed by the new sched_ule.c, I've noticed however that the WCPU field in top sometimes exceeds 100% (this wasn't the case with sched_4bsd).
