The reason is that 8-STABLE fails to stop scheduler on panic that breaks writing of crashdumps. 8.3-STABLE has new sysctl kern.stop_scheduler_on_panic. You should set it to 1 to get crashdumps saved. One more: does your box has PS/2 keyboard or USB? It matters too. For systems having USB keyboard there is another patch needed to obtain crashdumps (by Andriy Gapon): http://www.kuzbass.ru/freebsd/patches/stop_scheduler_on_panic.usb.diff Eugene Grosbein _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
