From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12 i586)

Description of problem:
Upgrading to kernel-2.4.3-12 causes my Xircom CardBus ethernet 2 100Mbps to
fail to operate under Full Duplex mode.  The network still works, but some
services do not work properly.  Most notably, a cvs client on this machine
fails intermittently.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. upgrade from kernel-2.4.2-2 to kernel-2.4.3-12
2. reboot with xircom cbe2 in pcmcia slot
3. watch network switch or hub light indicate link is not running in full
duplex mode
	

Actual Results:  Services which require full duplex don't work, or work
sporadically.

Expected Results:  Should operate in full duplex mode.  kernel-2.4.2-2
worked fine

Additional info:

Here's my /var/log/messages output for kernel-2.4.2-2 (where full duplex
works fine):

Comment 1 adi 2001-10-30 04:51:53 UTC

I just upgraded to kernel-2.4.9-6 and now my pcmcia xircom cbe2-100 card works
fine in full duplex mode.  It must have been a problem with the driver you
released in the 2.4.3 kernel.  But now it's fixed in your 2.4.9 kernel.  Thanks.
