http://bugzilla.opensuse.org/show_bug.cgi?id=963850 Bug ID: 963850 Summary: kernel 4.4.0 causes application lockup and unusable interfaces with radeon hardware Classification: openSUSE Product: openSUSE Tumbleweed Version: 2015* Hardware: Other OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: jimmy@boombatower.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.82 Safari/537.36 Build Identifier: [reply] [−] Description boombatower 2016-01-27 04:10:16 UTC Created attachment 121320 [details] sh -c "cat /proc/version; ./scripts/ver_linux; cat /proc/cpuinfo; cat /proc/modules; cat /proc/ioports; cat /proc/iomem; lspci -vvv; cat /proc/scsi/scsi" > env_info While running Plasma 5 on 4.4.0 the following occurs periodically: - chromium locks up - plasma desktop locks up - unable to enter password on plasma lock screen A trigger for locking chromium up seems to be to resize the window by dragging to screen edges (top to fullscreen, left to tack up left half of screen, etc). Otherwise, it also seems to somewhat randomly freeze over time. Reverting to 4.3.x resolves the issues. See upstream bug I filed: https://bugs.freedesktop.org/show_bug.cgi?id=93879.
