Netgear FA310TX Problems

[Bob Farmer]

Set the "max_interrupt_work" parameter to the driver module to turn off
the "Too much work during an interrupt" check.  I use "options tulip
max_interrupt_work=10000" in /etc/conf.modules.  It seems a higher
max_interrupt_work value is necessary on any machine with heavy network
traffic, at least in my experience.

The other error seems to be a problem with the PNIC chip, at least in the
Asante cards we have.  Older Asante cards with a real DEC chip didn't do
it.  For me, it only happens with both ends are at full-duplex.  Could it
be that when you put that switch you mention in, you're using half-duplex
on one or both ends at that point?  Whereas, without it, you're using
full-duplex?
