The atomic allocations for incoming packets probably overwhelm the memory
system. Try to increase the values (*2,*3) in /proc/sys/vm/freepages,
that'll keep more memory free for interrupts and flush more aggressively.
It may also help a bit to change the rx_copybreak argument of the network
driver.
