I get these alot nowadays under 2.3.25:
[excuse long lines] Nov 2 23:23:19 narayan kernel: UDP: bad checksum. From 194.47.218.125:137 to 194.47.219.255:137 ulen 76 Nov 2 23:25:59 narayan kernel: UDP: bad checksum.

Given the port numbers, these are some kind of chatting between the various windows boxen on my network. However, I don't remember seeing the errors before, and find it unlikely that there be so many checksum errors and only on packets of that kind (I do quite a lot of UDP traffic). Since I don't use the protocol in question I haven't noticed any possible adverse effects.
This is on a cheap ISA NE2000 clone on a 10BASET switched network.
