Aside from things being remarkably slow, it's remarkably stable. ;) Threaded X apps or no, I'm running a July 19 kernel with no instant reboots. PREEMPTION disabled, WITNESS enabled (I misspoke in another message when I said WITNESS was disabled---apparently I fiddled more than I had remembered). Toggling DRI back on and restarting X/kdm reboots immediately. Geoff
