Hello,
I seem to be suffering from some rather consistent panics. I say
consistent not because I can actually reproduce it on demand, but that I
know it _will_ happen eventually. These only happen while I am at the
office with my laptop. The only difference between the office and home
is the wireless network. I have an atheros based card in my laptop (and
using wpa_supplicant), and we have two wireless access points here at
the office. I'm not sure why there would be some problem, but if I
disable card the panics stop. I do notice that the two access points
have similar S/N ratios given my proximity to both. And that my machine
frequently flip flops between the two.
What happens is, two maybe three times a week my machine will panic here
at the office. Frequently when shutting down (when ath0 goes down),
sometimes when starting X, sometimes when killing X, sometimes while
sitting at console not even logged in, and sometimes after a reboot from
a panic while fsck'ing. All seemingly go away if I disable the atheros
card in bios.
I have a dozen crashdumps. I'm including dmesg, and a couple
backtraces. I'm not particularly familiar with the kernel sources so
not sure what I'm looking for here. Given the wide variation in bts, I
suspect folks are gonna say my memory is to blame. Possible of
course.... but odd it only happens at office. And only in RELENG_7,
never before in any prior versions. Ideas appreciated.
Thanks in advance. (dumps below, dmesg is last)
--=20
Regards,
Eric
