Yes, only the kernel needs to be updated. Look at rev 1.80
of /sys/compat/linux/linux_stats.c and related changes
(commited on 2006/05/05 16:10:45). I am reasonably certain
this is the culprit. To avoid looking at alpha support
removal changes (which have nothing to do with this) do
cd /sys/compat/linux
cvs diff -D'1 month ago' -D'1 week ago'
This is the only change in that time period. Perhaps the
commit (sponsored by IronPort Systems) needs to be vetted.
Removing this code has fixed the problem for me. If you
have an alternative fix I'll be happy to try it.
