We bugged SUSE support to get this fixed and received a special kernel
(3.0.101-0.40.1.7689.1.PTF-default). This is for SLES 11 SP3.
Folks with a SUSE support contract may open a ticket with SUSE to get it.

Also, it looks like an engineer at Yandex independently submitted a
fix in January which is now in Linux 3.19. As of this writing it's
only in mainline and not yet in the stable kernel:
