Tried 12.09 release:
http://releases.linaro.org/12.09/ubuntu/leb-panda/lt-panda-x11-base-precise_ubuntu-desktop_20120924-329.img.gz
Board: Pandaboard (rev A4)

This problem is still there and seems to affect both OMAP4430 and
OMAP4460 based Pandaboards.

I also noticed something like this during boot, not sure if relevant as glmark2-es2 works:
[   30.170227] [ INFO: possible recursive locking detected ]
