Bug ID: 72701 Summary: Screen freeze when using radeon driver Product: Drivers Version: 2.5 Kernel Version: 3.13 and 3.14 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: banjacnikola@openmailbox.org Regression: No
I got this problem with all distributions using new kernels, that I tried to boot from live CD, as well as the ones I have on the hard drive. Faster booting ones manage to boot before they freeze, while slower ones freeze in the middle of booting process.
