Ok, at the tail end of the dmesg file I am getting complaints starting at
boot time of non-sleepable locks held. My source is current as of 12 hours
ago. Pasted here is one of the errors:
checking stopevent 2 with the following non-sleepable locks held:
exclusive sleep mutex sigacts r = 0 (0xc1d39aa8) locked @
/usr/src/sys/kern/kern_condvar.c:289
checking stopevent 2 with the following non-sleepable locks held:
exclusive sleep mutex sigacts r = 0 (0xc1d39aa8) locked @
/usr/src/sys/kern/subr_trap.c:260
checking stopevent 2 with the following non-sleepable locks held:
exclusive sleep mutex sigacts r = 0 (0xc1d39aa8) locked @
/usr/src/sys/kern/subr_trap.c:260
Thanks for the help
Francis
