Bug Description
On an up-to-date install of Feisty on PS3, enable huge tables with:
mkdir -p /huge
echo 10 > /proc/sys/
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).

I have no idea what's going on, but could you try with 7.10 if it's any better?
