I've got a 3com 3C905 (Boomerang) that's having some problems under kernel 2.4.21. When the 3c59x module is first loaded after boot, it works fine. When I unload it, though, I can't reload it and have it work; I have to reboot the machine to get the card working again. The second time I try to load it, the module loads, but I get the following messages in my logs: Apr 23 09:14:13 gleipnir kernel: 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html Apr 23 09:14:13 gleipnir kernel: See Documentation/networking/vortex.txt Apr 23 09:14:13 gleipnir kernel: 00:0a.0: 3Com PCI 3c905 Boomerang 100baseTx at 0xe400.

At this point, I'm unable to ping anything, even machines on my local LAN, until the system is rebooted (either cold or warm boot works). I continue to get similar messages about transmit errors, except that Tx status register is 90 instead of d0. My first instinct is to blame the driver--especially as it's only on the second module load that problems occur.
