Hi All,
My first `panic' since 1995 ! - The title says it all.
My system is current as of July 19/99, the last working kernel was built
on (or about) June 8 - so I guess something broke between then and now.
The panic happens sometime after the disks get mounted but before the
network starts up. If it's useful I can pepper my `/etc/rc' file with
printf()'s.
I've attached gdb traceback info and my dmesg output ... If there's any
more data you'd like me to forward, just ask. :)
Btw, I'll be in meetings until about 3pm EST tomorrow, err today, so won't
be checking mail until then.
Cheers,
Andrew.
