next in thread | raw e-mail | index | archive | help
For some time, I've had trouble with -STABLE crashing sometime after
resuming on my laptop. The crash occurs within a minute or two after
resuming; it's normally coincident with network traffic (say IRC
reconnecting); and it always happens after the pccard (wi0) probes and
attaches and after dhcp has sync'd.
So... I finally got around to putting debug symbols in the kernel and
waiting for the crash again. I'm attaching the gdb -k output here. I
don't know what the large number (15 thru 33) of unresolved stack
frames are --- are they kld things? I have the following things
loaded:
[1:1:301]root@canoe:~> kldstat
Id Refs Address Size Name
1 5 0xc0100000 2b88e4 kernel
2 1 0xc03b9000 75c0 if_wi.ko
3 1 0xc187b000 7000 linprocfs.ko
4 2 0xc1922000 14000 linux.ko
5 1 0xc18ee000 2000 rtc.ko
... anyways... I'd like to track down this problem. Any ideas where
to start?
