tg3 and machine lockup?

I was running 2500 pps tx+rx on a 100bt port, with a tg3 in
the same machine. 1000 tcp connections, memory pressure, and
cpu was max'ed out.

I plugged in the tg3 to a e1000 (via cross-over cable), and then, or
very soon after that, the machine hung solid (or, maybe it tried
to spew to console..was on kvm and not selected..)

Last thing I see in the /var/log/messages is tg3 saying flow control
is on for tx and rx.

Now, it could be one of a million things...but just curious if anyone
else has seen anything like this.  Kernel is 2.4.20 + my hacks.

Take it easy,
Ben

There were tons of locking fixes to the tg3 driver
in 2.4.21

Cool, just moving to that now.  Will let you know how it goes.
