Can you get a coredump and a backtrace? That would be very helpful in debugging. > Now please give me a hint what to do.

Sounds very much like you damaged the drive. regards, le -- Lukas Ertl eMail: [EMAIL PROTECTED] UNIX-Systemadministrator Tel.: (+43 1) 4277-14073 Zentraler Informatikdienst (ZID) Fax.: (+43 1) 4277-9140 der Universität Wien http://mailbox.univie.ac.at/~le/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
