Subject: swapper: page allocation failure (2.6.19.2/x86_64)

This morning I got some oops after heavy disk and network I/O on a linux
2.6.19.2 x86_64 machine (Athlon64 3000+). One of the NICs is a natsemi.
Apparently disk read/write operations were affected as some applications
would report write/read failure 'Cannot allocate memory'.

All oops including this one can be found in the attached log file...
