--- Comment #8 from Winston Weinert winston@ml1.net --- I have experienced issues with TF2 and my Radeon HD 7770 hanging, with the same error messages.

I did follow the instructions to check for a VM error, but I found nothing in the dmesg output. I've attached it in case you still would like to look at it.
