This change appears to remove the panic that I was running into, but at the cost of increasing ithread scheduling latency, and as such is a temporary band-aid until jhb has a chance to resolve the ule<->preemption interaction that is the source of the problem. If it doesn't fix the problem for others-- sorry! Revision Changes Path 1.113 +2 -0 src/sys/kern/sched_ule.c
