next in thread | raw e-mail | index | archive | help
I have been getting frequent kernel panics for the last 5 days or so
in 3.3-RC.
The latest panic is with the 3.3-RC source as of about Sept 11 22:00 PDT.
This box in question is doing NFS for 2 workstations (only one is
really being used), and running named, squid and ppp -nat for my home
LAN. It seems to panic about half way through a make buildworld every
time.
I would be more than happy to provide more information as necessary.
I'm by no means a kernel hacker so I'm not really sure exactly what
info is needed.
I'm trying to reproduce this panic yet again with a kernel compiled
with debugging symbols so I can run it through kgdb.
For now this is all I have, but more info may follow.
Below is the dump and my dmesg:
Fatal trap 12: page fault while in kernel mode
