Choosing the previous kernel version fixes the problem. I had a bit of a trouble configuring grub to show the menu, but once I got that figured out, I just chose version 2.6.32.35-24
The problem version was 2.6.32.35-25 I wish there was a simple command to "rollback" the last kernel update so that one can run it in such a situation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/703352 Title: [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
