I began seeing this very thing around 2.6.24 time. (Fedora 8, vanilla
kernel.) I could usually cause the gnome terminal to hang if I rapidly
resized the window while executing make check-headers.
Over a couple of days I bisected it down to this commit:

hrtimer: unlock hrtimer_wakeup
hrtimer_wakeup creates a
base->lock
rq->lock
lock dependancy. Avoid this by switching to
HRTIMER_CB_IRQSAFE_NO_SOFTIRQ
which doesn't hold base->lock.
This fully untangles hrtimer locks from the scheduler locks, and allows
hrtimer usage in the scheduler proper.

Reverting the commit seemed to fix the problem for me.
Then I went away on a business trip Monday morning and returned Tuesday
night to a dead computer (won't POST), so I can't do any further
troubleshooting until I get it fixed.
Try reverting that patch and see if your gnome-terminal freezes go away.
