This crash looks very similar to #1301649. However is does not require the system to go into power save.
The crash is in radeon_ring_backup which is in linux/drivers/gpu/drm/radeon/radeon_device.c and part of the linux (kernel) package. I have added that package to this bug. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1746232 Title: driver looping then crashing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746232/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
