I have this exact same problem. My computer logs : WARNING: CPU: 3 PID: 659 at /build/buildd/linux-3.19.0/drivers/gpu/drm/i915/intel_display.c:9705 intel_check_page_flip+0xa2/0xf0 [i915]() WARN_ON(!in_irq()) continually with the 3.19.0-7 and 3.19.0-8 kernels in the -lowlatency kind.
It occurs sometime while resuming from pause in the -generic kind of kernel. I concur : https://bugs.freedesktop.org/show_bug.cgi?id=89321 seems to have the answer. Even a patch there. ** Bug watch added: freedesktop.org Bugzilla #89321 https://bugs.freedesktop.org/show_bug.cgi?id=89321 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1430230 Title: Log flooding with warning message when using linux-lowlatency kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1430230/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
