I get the "failed to reallocate TX buffer" message. Not all are related to the
page allocation failure. I am also getting "b43-phy0 debug: DMA RX:
setup_rx_descbuffer() failed" messages.

So far, the numbers printed by the revised printk are:

kernel: phy0: failed to reallocate TX buffer 0, 404, need 0, 0
kernel: protocol 0008 is buggy, dev eth1

kernel: phy0: failed to reallocate TX buffer 0, 1728, need 0, 18

Device eth1 is the b43 wireless device.
