That seems to be the case, as my laptop shows about an 80-85 % chance of experiencing a panic if left idle for long-ish periods of time (2 to 4 hours). I usually rebuild world or big ports overnight, and more often than not I wake up to a panicked machine, same situation every time: ... rman_get_bushandle() at rman_get_bushandle+0x1 sched_idletd() at sched_idletd+0x123 fork_exit() at fork_exit+0x12a fork_trampoline() at fork_trampoline+0xe ... The kernel/userland is rebuilt, the ports are finished compiling -- it's in the time AFTER the completion of all tasks that the machine gets bored and tries to kill itself :) I have seen the AC adapter plug/unplug "hang" in the past on this laptop, but I never made the connection between the events, as nowadays my laptop usually stays plugged in :( Attilio, I hope you can track this one down, let me know if I can do anything to help or test... -Brandon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
