same problem here. i left my laptop on for a longer time and ifconfig 
failed too
kernel backtrace same as above. kernel looked like it didn't swap out 
some memory.
lots of swap free no phys mem free. i dont know if this helps.
reloading the module didn't help too.
if you want more info please let me know
