There was a previous discussion of this message which concluded that it
must be a kernel bug:
http://www.postgresql.org/message-id/flat/CALXbVnehCf4XX1umL=ZJ+RJ5OO_DQagNiVubt48h0B6oOL2swQ@mail.gmail.com

I'd suggest reporting it to your kernel vendor and see what they say.

Also, when reporting kernel bugs:
*) Whether or not the system is virtualized (and if so, by which VM
system) is extremely relevant
*) Please report O/S vendor and version
*) Consider listing loaded kernel modules.  Exotic storage and network
drivers are especially interesting (say, fiber channel HBA or TCP
offload).
*) Research similar reports both internally within the archives and in
general.  If anything is found supply it as context with the report
*) It's helpful to rule out hardware problems.  If it's possible to do
so, run some hardware diagnostics

check out this thread and see if it applies (via google search,
