Are you _sure_ the hardware is good?

Well, it lasts on 2.6.10 indefinitely (since 1/1/5 minus the recent
upgrade attempts).  And the hardware itself has been in service for
a few years without failure.  It will last on 2.6.11 or 12-rc over
the weekend fine, but as soon as traffic picks up during the workday
it keels over.

Are you running anything which would cause netdevs to be destroyed? 
Bringing virtual devices up and down?  TUN/TAP driver?  Bonding driver? 
Anything like that?

The box runs keepalived (for VRRP), and quagga (for OSPF).  Neither should
be destroying netdevs during normal operation AFAIK.

Have you tried CONFIG_DEBUG_SLAB and/or CONFIG_DEBUG_PAGEALLOC?

No - do you think it would reveal anything given the above?
