This is the same problem, with a more direct error message.

The driver cannot get memory from the kernel to fill the Rx descriptor
list.  Presumably the kernel has temporarily run short of memory due to
bad VM/memory-management parameters.

Tune the parameters in /proc/sys/vm/bdflush as described a few days ago
to avoid this performance problem.
