watchdog timeouts

I just got a 3C575 PCMCIA card for my laptop, running a week old
-CURRENT.. Whenever transferring files from the laptop to another host
I'll see this error in my log:

Jan 16 20:05:12  kernel: xl0: watchdog timeout

And sometimes accompanied with these:
xl0: transmission error: 90
xl0: tx underrun, increasing tx start threshold to 120 bytes

And transfer speed will drop significantly (from 6-7MB/s to 200-300Kb/s)
- unplugging the card and inserting it again will fix the problem.

Any ideas ?
