Subject: [BUG] timer.h

Hi,

today I got the following kernel bug while wpa_supplicant tried to 
connect to my AP. Kernel is a self-compiled 2.6.22 running under Ubuntu 
Feisty.
The wireless device is a r8187 USB, the driver is patched for injection 
capability taken from www.aircrack-ng.org.
Don't know if this bug is related to the driver or to the kernel, I'm no 
expert.

Attached is the full dmesg and .config. Please CC to me, I'm not on the 
list.
