https://bugzilla.kernel.org/show_bug.cgi?id=199357 Bug ID: 199357 Summary: amdgpu: hang a few seconds after logging in, most likely due to regression Product: Drivers Version: 2.5 Kernel Version: v4.16 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: master.homer@xxxxxxxxx Regression: No Created attachment 275291 --> https://bugzilla.kernel.org/attachment.cgi?id=275291&action=edit Kernel log of the hang/crash I've been testing kernel v4.16 on my computer, but it's basically unusable - because after a few seconds or so after logging in it will do a soft lockup, and I can't even switch to VT. I was, however, able to ssh in to it, which is how I was able to get the kernel log. Right as the hang happened, I can see this in the log: Apr 11 14:04:13 homer-desktop kernel: [ 45.532038] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:45:crtc-1] flip_done timed out Apr 11 14:04:23 homer-desktop kernel: [ 55.772028] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [PLANE:37:plane-1] flip_done timed out Apr 11 14:04:33 homer-desktop kernel: [ 66.012282] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [PLANE:44:plane-7] flip_done timed out and after that is the regular kernel crash. I have tried this on both v4.16 and v4.16.1 with the same results. However, it doesn't happen on v4.15 (which is what I'm running now). So there must be some kind of regression between those releases. I am running stable KDE neon (which is based on Ubuntu LTS) with precompiled kernels from the ubuntu mainline ppa. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
