If you have physical access to the box try compiling in DDB and hit Ctrl-Alt-Esc on the keyboard when it freezes. If it drops into DDB then it isn't a hard lockup, at least. If you do get into ddb, capture the output of the 'tr' command. I'd also suggest setting up a serial console to capture any output that may be occuring at the freeze point .. if you also compile with BREAK_TO_DEBUGGER then you can trigger ddb from the serial console with a serial break as well... -- Doug White | FreeBSD: The Power to Serve [EMAIL PROTECTED] | www.FreeBSD.org _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
