We've had a lot of problems with the 3C905C cards under Linux; maybe it was just a bad batch, but they don't seem to be as good as the 3C905B cards- I suspect that the C stands for 'cheap'.
I'd suggest getting rid of it if you can, 'cos they're also really slow.

We use 3C905C and 3C905B here and never had problems. None of them is slower than others. This is independend of the kernel (2.2.x and 2.4.x). And one machine has additional cards: ne1k-isa and 3c59x (combo)!
Did you check your cables and switch? ping -f is a good thing to check your LAN

Perhaps they were a bad batch, but we're using 3com switches and a mixture of other 3com and unbranded cards and haven't had problems with them. The problems seem to occur in full-duplex mode under high load, when you get a lot of collisions-- surely that shouldn't happen with switches? I notice that the 3C905B cards use a Lucent chipset, but the C cards use one made by a company called Broadcom William
