The transmitter stopped!

Hello, we're using NetGear FA310TX (Tulip 21140A) on 440BX SMP
motherboards. We're getting the hung-on-big-loads problems, symptoms
varying from total lookups to network freezes which are solved by
doing a "ping -f" against the machine and then ifconfig down&up on the

Just upgraded to Linux 2.1.121 (SMP) and Tulip.c v0.89K and are having
the same problems, but noticed a syslog message -- "transmitter
stopped", right after the cards are detected.

What causes this?  Is it related to the network freezes?

Do anyone run MPICH successfully on Tulip clones with Pentium II and
BX chipset?  The problems we see are reproducable, and occurs when
running the NAS Parallel Benchmark. I'm unable to reproduce this
problem with ttcp.

I'm also getting the same problems without SMP, ie using a
uniprocessor kernel.

If I can do anything to help debugging this, please let me know!
