Timeouts on 3C575 network device

[Steve Snyder]

I'm getting transmission time-outs on my CardBus network device, as shown 
below.  

My PCMCIA/CardBus support is built into the kernel.  Although the info 
shown below was generated by a 3CCFE575BT, I get the same behavior when 
using a 3Com 3CXFEM656C.  

I have been seeing this same behavior for years, previously with kernel 
v2.2.x and the pcmcia-cs code seperate, and now kernel 2.4.x with the 
pcmcia code integrated.  Now, with all those different code revisions and 
the problem still remaining you might suspect that it is a hardware 
conflict.  If that's the case, then why is this same hardware problem-free 
in Win98 (I have a dual-boot machine)?  

This problem is very reproducable.  I can't state a sequence of steps to 
reproduce it, but I can generate as many errors loggings as you'd like just 
by using the device.  Please let me know what further info is needed to get 
this problem fixed.  

Thank you.
