Created attachment 163301 [details] dmesg showing intel_check_page_flip Intel G45 based system has experienced a "WARNING: CPU: 1 PID: 0 at drivers/gpu/drm/i915/intel_display.c:9916 intel_check_page_flip+0xc2/0xd0 [i915]()" upon updating to the 3.18 series of kernels. Complete dmesg output is attached. I am currently running the machine with the drm.debug=14 kernel parameter and will update the attachment with the output when the same error is thrown again. Until this, I hope the attached will help provide some clues as to the nature of the crash. The kernel version is 3.18.2 from Arch Linux which does incorporate D. Vetter's patch[1] found from this[2] bug report. Googling on the error found this bug report[3] against Fedora, so I am not the only one experiencing it. 1. http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d472fcc8379c062bd56a3876fc6ef22258f14a91 2. https://bugs.freedesktop.org/show_bug.cgi?id=76554#c116 3, https://bugzilla.redhat.com/show_bug.cgi?id=1174009

Mmmmh, that seems to have been backported to v3.18.4 and later already, can you double check and reopen if the problem persists with that?
I haven't run into it since my report in comment 4 and that machine is now on 3.18.7. I will repoen if I experience it again.
