3c59x transmit error

[Kelledin]

I've got a 3com 3C905 (Boomerang) that's having some problems under kernel
2.4.21.

When the 3c59x module is first loaded after boot, it works fine.  When I
unload it, though, I can't reload it and have it work; I have to reboot
the machine to get the card working again.

The second time I try to load it, the module loads, but I get the
following messages in my logs:

At this point, I'm unable to ping anything, even machines on my local LAN,
until the system is rebooted (either cold or warm boot works).  I continue
to get similar messages about transmit errors, except that Tx status
register is 90 instead of d0.

My first instinct is to blame the driver--especially as it's only on the
second module load that problems occur.
