This occurs when the driver is using   dev_kfree_skb()
call instead of the newly introduced   dev_kfree_skb_irq()
call inside an interrupt handler.

This was changed in  tulip.c:v0.92x 8/7/2001, as well as in most other
drivers around early August, so you aren't quite using the latest driver.

The volume of warning messages is the only real problem.  Updating the
driver should eliminate the messages.
