From https://bugzilla.redhat.com/show_bug.cgi?id=1481365 Description of problem: Using KVM, QXL driver emits error message over and over, I never get to my home screen. It seems to be happening while attempting to switch resolution. Another user reports that everything works if he uses 1024x768. Version-Release number of selected component (if applicable): 4.12.5 Steps to Reproduce: 1. Remove "rhgb" from kernel command line because of a possibly different QXL bug (don't have the link right now.) 2. Boot into graphical mode under KVM. Login screen appears, try to log in. 3. Desktop never appears. System log keeps getting these messages: Aug 13 14:03:40 localhost-live kernel: f 4026531862#140: failed to wait on release 22 after spincount 301 Aug 13 14:03:41 localhost-live kernel: f 4026531862#140: failed to wait on release 22 after spincount 301 Aug 13 14:03:41 localhost-live kernel: f 4026531862#140: failed to wait on release 22 after spincount 301 Aug 13 14:03:41 localhost-live kernel: f 4026531864#142: failed to wait on release 24 after spincount 301 Aug 13 14:03:42 localhost-live kernel: f 4026531864#142: failed to wait on release 24 after spincount 301 Aug 13 14:03:42 localhost-live kernel: f 4026531864#142: failed to wait on release 24 after spincount 301 Message is from drivers/gpu/drm/qxl/qxl_release.c::qxl_fence_wait() DMA fence operations are timing out. System can be shut down normally from the VM monitor, it's not frozen. The VM is only usable in text console mode.
Hi, Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org. To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default). Sorry about the noise!
