Getting back to the core (this is also reproducable under Debian back

Your patch and the changes in kernel 3.5 which they're based on fix
the reboot but it's still a heavy DoS against the Box (Alix).
Smashing 70 mbit with 64 byte packets against using pktgen makes the
loadavg go above 50 and the system unresponsive while "under attack"..
Better than reboot but not good..
Any hints where to proceed to fix this?
There's another patch at
http://www.mail-archive.com/[email protected]/msg06544.html
that also claims to fix the lockups and reboots. That one also fiddles
with RX_RING_SIZE and polling a bit, along with adding memory barriers.
Maybe it's worth testing that patch too?
