I just tested this on my Netra-X1. 

I am seeing occasional Kernel unaligned access messages as follows

Kernel unaligned access at TPC[5e4420] ip_rcv+0xd0/0x58c
Kernel unaligned access at TPC[517f84] ip_fast_csum+0xc/0x80
Kernel unaligned access at TPC[517f88] ip_fast_csum+0x10/0x80
Kernel unaligned access at TPC[517f8c] ip_fast_csum+0x14/0x80
Kernel unaligned access at TPC[517f94] ip_fast_csum+0x1c/0x80

These repeat something around every 6 seconds (although it often
varies). I've dumped the network traffic (both from the box itself
and from another) and I cannot see any obvious traffic pattern that
causes things to break.

I suspect that the problem has something to do with the tulip network
driver but do not have any better clue than that. I guess that I need to
log this as a bug.


1 - the network is actually usable even with the issues (not surprising
the messages are just the kernel telling us that it has "fixed" the

2 - I had seen a similar thing with an earlier 2.6.18 kernel but at that
time I couldn't be sure whether it was my compilation environment that
was causing it.
