Whatever comes from the Angstrom/meta-ti master branch these days:

root at beagleboard:~# cat /proc/version
Linux version 3.2.18 (cbrake at happy.bec-systems.com) (gcc version 4.7.2
20120706 (prerelease) (GCC) ) #1 Thu Aug 16 08:50:30 EDT 2012

I'll try to do more systematic testing ...

Is there another kernel I should try?
