next in thread | raw e-mail | index | archive | help
Hi!
I'm wondering if any of the hackers is able to take a look at this panic?
The following panic occurred while trying to reload pf rules. The
reload was needed as `pfctl -sq' gave me something like 'bad file
descriptor'. I haven't seen these panics for a while now but months
ago I've had a lot of trouble using altq + netgraph/mpd and the system
panic'ed every time reloading rules (with queuing). Probably this is
also netgraph related again.
Also I'm wondering why kgdb doesn't give me the panic message on
startup (it's taken from dmesg, the backtrace is taken from kgdb as it
also contains source code line numbers).
Machine is 6-STABLE, csup'ed and compiled 20 days ago.
Thx!
Volker
