As it turns out, this isn't a problem with eventtimers in any way, sorry for the confusion. I had checked out and built a completely clean RELENG_9_0_0_RELEASE so that I could be sure I was testing against the offical release before telling the OP "I do/don't see similar problems." As it turns out, one of my local hacks is required if I want use the RTC clock for anything (buggy old hardware). Once I applied that patch, I can now switch eventtimers without any problems. -- Ian _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
