About error number, it is -110. erro message is below

About sending large data problem, I add more kernel network buffer to fix
it, it seems work.
sysctl -w net.core.wmem_max=12582912

==============================
============================
I use this WNIC in a s3c6410 devboard called OK6410 made by
forlinx(http://www.forlinx.net/Other/6.htm)

The kernel is 3.0.1, the driver in the kernel source can't work. So I
tried compat-wireless-3.3-2-n and
compat-wireless-3.5.4-1. 3.3-2 is eaier to get -101 error when I load
the modules, in this time I have to replug WNIC card.

When networking is connected, I can't ping ar6003 in the other place,
if ar6003 didn't send any data
recently.Once ar6003 stoped sending, I can't send to ar6003 after a
very little while.

But if I send large data like video both of them still stop working
after a while, 3.3-2(about 5 minutes) seems to work more longer than
3.5.4-1(about 1 mintue). But both ip link and iw wlan0 link show my
link is up. I have to ifdown and ifup to use wireless again.

kvalo said it cause by irq problem.But when I compiled compat-wireless

kvalo said it cause by irq problem.But when I compiled compat-wireless
with debug, I only have files in /sys/kernel/debug/ieee80211/
phy0/ , but there is ath6kl directory there. I have enabled all
debug_mask, but I don't get any irq infomation frome dmesg.

Could you tell me the correct way enable debug in compiling and load module?
P.S how to install compat-wireless? I can't use INSTALL_MOD_PATH, I
have to copy these directory and use find tool to remove .c .h .o
files.
