Thanks again. From the first look the suspend/resume routines of the driver
are missing some calls. In particular, with the IRQ-freeing patch for yenta it is
likely to get an out-of-order interrupt as I suspected.

Linus has apparently dropped that patch for yenta, but in case it is
reintroduced in the future you will probably need a patch to make the network
driver cooperate. I'll try to prepare one tomorrow, if I can, but I have no hardware
to test it.
