Can you all *PLEASE* report what cpu you have with these problems as well as your compiler and what cpu you selected in kernel compliation?
It appears to be a checksumming problem, and Linux has asm optimizations for packet checksumming, so perhaps there is a bug in one of the checksumming routienes.. Davem?
FYI-
PPRO 2.2.3 compiled w/ GCC with PPRO as kernel cpu type: OK CELERON 300A 2.2.5 compiled w/ GCC with PPRO as kernel CPU type: OK
