Here is a temporary patch sent by Paul. I patched 8390.c to prevent it
from being interrupted as a temporary "fix" to get on-the-air.

On UP boxes, it happily runs bottom half handlers while in an interrupt,
which has caused the "eth0: Tx request while ISR is active" messages.
The following two line patch fixes that problem. Looks like a simple
thinko-typo. You can decide if the atomic ops are really required or
just overkill :)

Paul.
