Whenever you give dmesg output you really should mention the kernel version.
Often the dmesg output changes between versions. Also you should mention the
hardware/driver you use.
I checked the source for the latest pcmcia drivers and noticed similar
messages in the axnet_cs.c driver. It appears to be from the card returning
the address to start reading which is not where it finished reading before.
So something strange is being done in the read buffers (could be a hardware
problem).
This isn't what I'd expect to see as a result of physical damage to the
PCMCIA bus. It is what I expect to see from a cheap network card that
doesn't work correctly.
I recently bought myself a cheap 100baseT network card that has similar
problems (which I have not yet debugged). I think that the real problem is
that there's a lot of junk hardware being sold.
Probably you should test it out in another computer to check if it's your
computer or the network card. But I'm willing to bet it would be your
network card.
