[OOPS] rt2x00: unplugging an rt73 device oops at usb_kill_urb+0x14/0xd0

[Nicolas Deschildre]

I tried the wireless compatibilty stack from the 5 June.
When unplugging a RT73 device from its USB slot, I get the following oops :

This is fixed in today's wireless-testing.
compat-wireless-2008-06-12.tar.bz2 appears to contain the fix already.
