Not good.  A "catastrophic error" due to PCI aborts.  I'm afraid this is
outside my experience.

What you could try is the latest 3c575_cb.c from the pcmcia-cs package. 
http://pcmcia-cs.sourceforge.net/ . This driver is derived from a recent
scyld.com version, but David has done some additional work on the 575. 
Some of this pertains to ASIC-specific bugs in some devices.  It may
help.

If you do try this, please be sure to let us know the outcome.

David uses a web message board at the above site for support - I'd
suggest you use that once you have tried his driver.  This is because
there may be some problems with your cardbus bridge - David understands
these beasties well. Be prepared to tell him the version of your laptop
and the details of the Cardbus bridge.
