More of them on http://krogh.cc/~jesper/kernel-messages.txt

The systems is a 32 core Opteron (8xquad-core) with 64GB of memory, but 
otherwise its just running PostgreSQL+apache+perl.

I hit the same one a week ago on 2.6.27.6 (see the 2.6.27.21 release 
thread here for that): http://lkml.org/lkml/2009/5/8/44

Any suggestions?
