Do you have debug info that'd point to a code line?
I have never heard of this.
I don't actually know how to get a line of code out of those
hex offsets...
Someone told me many years ago..but I lost that information :P
Err, I never remember either, I think Luis knows the gdb thing ... I
usually use "objdump -dS"
gdb net/mac80211/mac80211.ko
l *(ieee80211_stop_tx_ba_session+0x14/0x84)
Oops I meant:
gdb net/mac80211/mac80211.ko
l *(ieee80211_stop_tx_ba_session+0x14)
Thank!
I had to re-compile with debugging symbols, and added kgdb (hopefully
that won't mess anything up).
You may want to look at using netconsole instead if you're goal is
just to get some oops off the box.
CONFIG_NETCONSOLE=m
mcgrof@tux ~/bin $ cat netconsole
#!/bin/bash
sudo dmesg -n 8
sudo ip addr add 192.168.4.2/24 dev eth4
sudo modprobe netconsole
netconsole="@192.168.4.2/eth4,@192.168.4.3/00:1e:37:82:48:5a"
I'd run that script on the dev box, and on 192.168.4.3 just do `nc -l
-p 6666 | tee log`. To test just modprobe and rmmod ath9k.
I have serial-console, is netconsole any better, or just useful
if you don't have serial console?
I was sort of hoping kgdb would magically drop me into a debug
shell on panic and let me look at backtraces and variables...but
instead the system would go OOM, hard-lock, or panic and show a single
line of panic and then dead to the world. I've enough to debug w/out
debugging kgdb as well :)
Thanks,
Ben
