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.

Hi Steve,
I have the same problem here (3c575 too, K6-2 too). Cardbus bridge TI1251B.
But I noticed that it nearly never occurs when I put my notebook in a cold
room. Also, it occurs more often when I have transmitted lots of data and the
notebook is hot. In my case, I believe it comes from the cardbus bridge not
coping with the card speed. Perhaps under windows the card is underloaded and
the bridge can keep cool ? but I definitely think it's a hardware problem first
and perhaps the software can mask it.
If you want to reduce the penalty of these timeouts, you can put this line
in your /etc/modules.conf : "options 3c59x watchdog=50". It prevents the
card from hanging more than 50 ms. But take care of your syslog !
Regards,
Willy
