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.

Looks like a duplicate, fixed by

commit 7d47559ee84b3ac206aa9e675606fafcd7c0b500

    drm/i915: Don't call intel_prepare_page_flip() multiple times on gen2-4

in v3.19. Thanks for the report, please do reopen if the problem occurs with v3.19.

*** This bug has been marked as a duplicate of bug 88381 ***
Comment 6 Jani Nikula 2015-02-11 13:55:37 UTC
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?
Comment 7 da_audiophile 2015-02-11 20:08:40 UTC
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.

Comment 9 da_audiophile 2015-03-09 11:49:01 UTC
Running 3.19.1 I have experience this bug again on this hardware.  Should I open a new ticket since this one is marked as resolved?

Comment 10 da_audiophile 2015-03-09 11:51:54 UTC
I found the status toggle and just realized that I can switch it back to 'reopened' which I just did.  Do you require that I boot with the debug flags and wait for it to happen again?

Comment 17 Rob 2015-06-19 00:49:06 UTC
Sorry, regarding comment #15 I meant to say 15.04 instead of 14.10
Comment 18 Jani Nikula 2015-10-07 11:00:54 UTC
We seem to have neglected this bug. Apologies.

If the problem persists with latest kernels, please file a bug at the freedesktop.org bugzilla [1], referencing this bug. Thank you.
