I can confirm this on Oneiric with latest updates. Bug occurs on system with long uptime, because of memory fragmentation.
Problem is described in details here: http://lwn.net/Articles/467328/
My solution was to disable synchronous memory defragmentation with:
echo never > /sys/kernel/mm/transparent_hugepage/defrag or less restrictive: echo madvise > /sys/kernel/mm/transparent_hugepage/defrag
This bug is found in other distributions, like Arch: https://bbs.archlinux.org/viewtopic.php?id=112846&p=4
