Enable dumpdev and dumpdir in rc.conf, here's the manual excerpt: dumpdev (str) Indicates the device (usually a swap partition) to= which a crash dump should be written in the event of a system crash. If the value of this variable is ``AUTO'', the first suitable swap device listed in /etc/fstab will be used a= s dump device. Otherwise, the value of this variable is passed as the argument to dumpon(8). To disable crash dumps, s= et this variable to ``NO''. dumpdir (str) When the system reboots after a crash and a crash dump is found on the device specified by the dumpdev variable= , savecore(8) will save that crash dump and a copy of the ker- nel to the directory specified by the dumpdir variable. The default value is /var/crash. Set to ``NO'' to not run savecore(8) at boot time when dumpdir is set. Then, when it crashes, inspect the dump. See here: http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-gdb.h= tml If you suspect it's a FreeBSD problem and not a hardware problem, you'll need to send debugging data similar to that in the example in handbook. --------------enigA9EE61F561D5C3C83995E28B Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkjM+pgACgkQldnAQVacBchpwwCeMz9Dx0b8H2G8yo4sDpFFPie+ Gd4AoObQWu29qJIge8y2hWQZUKkB4Jvb =r/MD -----END PGP SIGNATURE----- --------------enigA9EE61F561D5C3C83995E28B--
