dmesg output with stack traces examples
Can't dupe a bug on another bugzilla, but it's this one: https://bugs.freedesktop.org/show_bug.cgi?id=89108 Hopefully will be backported to v3.19.y.

Thank you very much for your quick and useful response. |
Created attachment 169921 [details] lspci -k -vvv Hello. After kernel upgrade from 3.18.7 to 3.19.1 I occasionally get stack traces related to drm_wait_one_vblank() in my dmesg. I haven't figured out the exact conditions for these traces to appear, but they tend to appear more often while browsing in Firefox or running VirtualBox. I had no such problems on 3.18.7. When these traces appear everything seems to run as usual, except for VirtualBox, which becomes very very slow. My OS is Gentoo amd64 with vanilla kernel 3.19.1. If you need any additional info I am ready to provide it.
