With the recompiled (fully from scratch) kernel with generic alpha vs
DP264 I am still seeing the same thing.
What is odd is that I see "dp264_srm_device_interrupt" in the error
though...
Next step is to make sure it's the tulip driver itself and not the
network stack. I can't use the i1000 card at the moment, so I need to
find another PCI nic to test.
