Comment(by bt4):
Thanks again for the info.
That previous test was using a module which Niko sent me as I am not sure
how to build the SHR kernel.
However, I have just built a kernel myself using the instruction at:
http://wiki.openmoko.org/wiki/Kernel
I inserted #define DEBUG and I could still reproduce the problem so I will
attach the files you mentioned.
Kernel details :-
r...@om-gta02 ~ $ uname -a
Linux om-gta02 2.6.29-GTA02_andy-tracking-mokodev #1 PREEMPT Fri Mar 5
21:28:42 GMT 2010 armv4tl GNU/Linux
uImage-moredrivers-GTA02_andy-tracking-a15608f241a40b41.bin
I haven't been able to reproduce this using a scripted method, only by
actually using NWA itself. It might be worth you installing it to try, as
I am sure you can reproduce the problem with different settings and
conditions also.

Comment(by PaulFertser):
Can't find NWA source anywhere. Neither it's mentioned on the
corresponding wiki page, nor it is present in OE recipies. :-|
I'll try to take a deeper look at the code in question and will provide
you with additional debugging patches. But the round-trip times of this
remote debugging thing are high :/

Comment(by PaulFertser):
And it looks very much like you didn't define DEBUG the way i expected.
Are you sure you inserted #define DEBUG _before_ including ar6000_drv.h?
I think i found the race though: ar6000_ioctl_siwscan checks arWmiReady in
the beginning but the device gets destroyed while waiting for scan
results. And the second wmi_bssfilter_cmd is called with ar->arWmi==NULL
:-/

Comment(by PaulFertser):
Please try the new patch (the old one is no longer relevant). Even if it
solves the problem, it still sucks (other parts of the driver have a lot
of similar "solutions" to avoid races) but i do not think anyone's going
to rewrite the driver :|
BTW, providing binary helped a lot, yesterday i errorneously thought that
it's the first bssfilter_cmd invocation that fails, and that drove me away
from more fruitful thoughts.
