Ethernet card intermittent problem (3com FE575CT on a TwinHead PowerSlim)
A TwinHead PowerSlim 600, running Debian 2.2, has a problem with its Ethernet
card, a 3com FE575CT. It works but, from time to time (after one hour or two)
the card is no longer usable: no IP packet comes out.

Rebooting the machine cures it. Sometimes, /etc/init.d/pcmcia stop + start clears the problem, too.
