Please someone enlighten me ;-) Try doing "sysctl debug.kdb.panic=1". That will forcibly panic your system. If you still don't get a crashdump, then it's not Gallium's fault. Also, check that /data/crash is mounted before savecore runs. -Alan > > Regards, > > --mikej > Michael Jung > > ___ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org" ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
