http://bugzilla.opensuse.org/show_bug.cgi?id=1176646 Bug ID: 1176646 Summary: Latest Kernel has i915 GPU Hang Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: erecio@polywog.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 841741 --> http://bugzilla.opensuse.org/attachment.cgi?id=841741&action=edit dmesg output The following kernel works fine with my i915 GPU (5.6.14-1). However, the latest kernel 5.7+ (kernel-default-5.8.7-1.2.x86_64) causes my GPU to hang and it flickers and can never login. Switch back to 5.6 and it works fine. There have been other reports on Fedora with the same thing. https://bugzilla.redhat.com/show_bug.cgi?id=1843274 I have attached my dmesg output. I use the zap option to kill the xorg server and kdm comes up just fine most of the time. Trying to login is no good though. Also I can ctrl-alt-f2 to go on command line just fine. So it seems to be xorg with the new kernel.
