Public bug reported:
On an up-to-date install of Feisty on PS3, enable huge tables with:
mkdir -p /huge
echo 10 > /proc/sys/vm/nr_hugepages
mount -t hugetlbfs nodev /huge
chown root:root /huge
chmod 777 /huge
When X (or the Gnome session) starts, the hard disc will begin
thrashing, top reports 99% CPU time spent waiting for IO completion, and
the system grinds to a halt.
Disabling X (ie, booting into console mode) with huge tables enabled no
such behaviour is observed (huge tables work, no disc thrashing).
** Affects: Ubuntu
Importance: Undecided
