No dump device defined. >=20 >=20 > This is a regular occurrence, but varies by source. Brand new fBSD > 6.3 machine, what more information do I need to provide? To be of any use we need a backtrace. See=20 http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug.html for details. First you need to configure a dump device then when the system crashes a crash dump will be written to /var/crash by default. You then run kgdb on the file to get the backtrace. --=20 Bruce Cran --Sig_/LFYfShDaoTJyD=dWb/8VWF9 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIUt+kn4uvqcJsLfgRAjX3AJ9nlV6dRofVMzKu4rYrtUAsB0X11ACfUfZv wduvrz9XeLZjiYMXbcruvSI= =Vce2 -----END PGP SIGNATURE----- --Sig_/LFYfShDaoTJyD=dWb/8VWF9--
