Perhaps a problem with the csum assembler implementations? Which cpu
type do you optimize for, and which cpu is installed?
Btw, are you overclocking anything?

I think the dump that i got suggests something more

No, i don't think so...i got the dump of the packet at the local_out and
post routing hooks& found it in bad shape there. Here it is what it
looks like:
45 0 0 80 0 0 40 0 ff 1 2d f8 c0 a8 66 16 c0 a8 66 1d 0 0 e4 48 11 d 0 0 14
Coudl the problem be in the NIC driver not in the alloc_skb? I have used
both 2.4.{1,3} for some time and never seen this corruption. I use ping
-f with various packet sizes for stress testing my IPSec boxes... these do
quite a bit of extra skb creation as an IPSec header sometimes does not
fit

What compiler are you using to compile the kernel?
