Hey, btw., you can only dump into a configured and/or active swap partition. So, you also need a `swap on' clause! j@uriah 693% fgrep kernel /sys/i386/conf/URIAH config kernel root on sd0 swap on sd0 and sd1 dumps on sd1 > I did. Before I started all this.

Seems you gotta contribute this to gdb yet. It shouldn't be too hard, since gdb can already handle all of the details (see the ``info line'' and ``disas'' commands). You ``only'' need to combine them. > That is good info, I didn't see anything like that. The panic message > printed the current EIP, then "waiting 15 seconds to reboot" or > something like that.

HP-UX is said to be much BSD inside. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
