Re: [Intel-gfx] "flip_done timed out" messages causing huge increase in boot time

Re: [Intel-gfx] "flip_done timed out" messages causing huge increase in boot time
I submitted the bug report at https://bugs.freedesktop.org/show_bug.cgi?id=109245 . The dmesg log is attached to the bug report.

Re: [Intel-gfx] "flip_done timed out" messages causing huge increase in boot time
Small omission on my part : I meant 4.19.12, not 4.19.2 as the last working version. Also, I can confirm that reverting 13947d150bae871bd880565ada318b0bcd0e690e from the current HEAD of linux-stable fixes the issue.

With SNB I would be tempted to blame the LP3 watermarks, but 4.20 already has commit 21556350ade3 ("drm/i915: Disable LP3 watermarks on all SNB machines"). Can you file a bug at https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel and attach the full dmesg from the boot with drm.debug=0xe passed to the kernel cmdline? -- Ville Syrjälä Intel ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
