Which driver version are you using? (0.95 or later is fine.)
What is the detection message?

The receiver is out of buffers, which usually means that the kernel has
run out of skbuffs. The kernel then spends a whole bunch of time and
cache misses trying to deal with no skbuffs, resulting in no CPU cycles
to keep up with the interrupt work.
This should not halt operation, although it will cause packet drops.

This is the restart message after we have some memory for the receiver.
