Sorry that I didn't mention this sooner. Hmm, it seems at least one person on current@ was already confused by this and asking if he should turn on FULL_PREEMPTION instead. We probably don't want people doing that. :-P Also, believe me that I haven't forgotten about the preemption stability problems. I just need to reproduce these problems on machines with a serial console. The only machine I can reproduce hangs on so far is my laptop which has no serial port. :( -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
