2.6.4 and 2.6.7 page allocation failure / e1000 related ?

["Christopher S. Aker" <caker@theshore.net>]

Hello,

I've had this appear in dmesg a few times on a number of different systems, all
identical hardware: SuperMicro 6013P-i dual Xeon, with 4GB of RAM, built-in e1000
NICs connected via 100Mbit switch.

It doesn't appear to cause any ill effects.  I haven't provided all the variations
of the messages, but the consistent thing between them are the e1000_* calls.
This isn't an OOM situation, the machines are only a handful of MB into swap (if
that).
