Description of problem:
I have two Tyan Thunder dual-Athlon machines, each with a 3com gigabit (ie
broadcom) card, connected by a 5e crossover cable.  Running ttcp between
them leads to a kernel oops by either the sender or receiver (which seems
to depend on setup); transferring files with something like scp lead to all
sorts of errror messages.

- behavior is the same for at least the last two rawhide kernels (2.4.7-2.9
and 2.4.9-0.5).  With the 2.4.9 kernel, I tried for reference three
different binary rpms, smp-athlon, smp-i686, and plain old i386 (one cpu).
- the same gigabit cards (and even the same cable) appear to work fine in a
similar setup, two Intel Stl2 dual-pIII machines, on both recent rawhide
kernels.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
steps seem to vary a bit, depending on which exact kernel I run.  here are
steps, results, and oops for with kernel-2.4.9-0.5.i386.rpm:
1. ifup ethx on each machine
2. ttcp -r -s on receiving end; ttcp -t -s -n 50000 on transmitting end
(default -n of 2048 doesn't trigger it).

	

Actual Results:  receiver oopses (with different kernels, I think it was
the transmitter that was oopsing)


Expected Results:  blazing speed

Additional info:

I captured the oops from a serial port. 
'ksymoops -m /boot/System.map-2.4.9-0.5 oops.txt' output:

else I should have done. )
