So, you press ctrl-alt-F2 in X and then alt-F7 in tty2 and after some cycling you have the beast. However, it also appears upon sleep/wake and connecting/detecting external (tried only VGA) monitors. I did not try 4.10.x sources as I'm in general reluctant to use unstable kernels. Also, I have no wish to downgrade to 4.4.x as these caused other and seems unrelated problems. At least I never had the described intel/drm issue on 4.4.x Guys at ARCH discuss the same, exactly the error as I have: https://bbs.archlinux.org/viewtopic.php?id=218581&p=3 They have some suggested solution (found on freedesktop.org) by adding video=SVIDEO-1:d to the kernel command line. This however made absolutely no difference to me. Also in my case no stalls during the boot or shutdown, only during the work. Any thoughts?
Well, tried and tested: gentoo-source-4.10.10 - the same problem with flip_done timeout. The only change is that CRTC:26 transformed to CRTC:31 but who cares? Had to go to gentoo-sources-4.4.61 - have chosen 61 as the one declared LTS on the kernel.org Testing, but no problem at least upon cycling tty2<->tty7(X) Will be testing more but hope to have an outdated kernel at least to a rescue. Any ideas how to fix this in upstream?
please try to use video=SVIDEO-1:d in the kernel boot parameter relevant: https://bbs.archlinux.org/viewtopic.php?id=218581 please test 4.10.12 gentoo-sources and see if there is still the message
Well, it was a long break from the everyday life but getting to the point: I did 4.10.12 and 4.11.3 gentoo sources and for both it is the same SVIDEO-1 trick does not help in either configuration. I can try 4.10.17 but why should I expect it is better? This my bug can be related to Bug 93782 as well. But there, if I'm correct, guys have trouble booting at all. I can boot the machine. SO, I have this in 4.9, 4.10 and 4.11 kernels. Any thoughts?
I meant Bug 93782 on https://bugs.freedesktop.org/show_bug.cgi?id=93782
We'll follow the upstream bug and backport any fixes, but they have provided a workaround and subsequently have deprioritized fixing this. (Workaround + old HW).
