https://bugzilla.kernel.org/show_bug.cgi?id=107381 Bug ID: 107381 Summary: radeon VCE init error (-110) -- AMD/Intel Mars Hybrid Graphics Product: Drivers Version: 2.5 Kernel Version: 4.3 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: schmod@xxxxxxxxx Regression: No Created attachment 192261 --> https://bugzilla.kernel.org/attachment.cgi?id=192261&action=edit dmesg output Since upgrading to Ubuntu 15.10, I have encountered graphics performance issues, and have occasionally experienced lockups during boot. I have encountered this issue on kernel 4.2.0 and 4.3.0, and it seems to have affected users on other distributions as well: https://bugs.launchpad.net/fedora/+source/linux/+bug/1512848 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=803087 https://bugzilla.redhat.com/show_bug.cgi?id=1262649 Notably, this issue seems to primarily impact users with The ATI "Mars" chipset, on machines that have an Intel/AMD hybrid graphics hardware configuration. This shows up in dmesg (full log attached, because there's a fair amount of seemingly-useful context): [ 4.917369] radeon 0000:01:00.0: VCE init error (-110).
