Looks like if you have been hit by more or less the same bug as I did. As for me I had to revert to default Ubuntu drivers temporarily since current version could lockup GPU in unrecoverable manner while running OpenGL games and it's quite easily reproducibe, unfortunately. GPU would not recover: after recovery attempt the very same problem happens immediately so GPU recovery happens every 10 seconds without any real success.
