Created attachment 109831 [details] the oldest instance of the tb I have (in abrt format) I'm running Fedora 18 on a 2010 model Sony Vaio Z, model VPCZ112GD, graphics adapter is a: 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) [ 58.460] (--) intel(0): Integrated Graphics Chipset: Intel(R) Arrandale The system also has an NVIDIA adapter - it slightly predates Optimus, it uses some kind of Sony-proprietary Optimus precursor, I think, but I have it firmware hacked to enable only the Intel adapter. The NVIDIA one does not show up at all in lspci or X log, so I don't think it's interfering. Ever since kernel 3.8.9-200.fc18.x86_64 , I've been consistently getting a traceback like this once or twice per boot: WARNING: at drivers/gpu/drm/i915/intel_display.c:1028 intel_wait_for_pipe_off+0xea/0x1b0 [i915]() Hardware name: VPCZ112GD pipe_off wait timed out I'll attach the oldest and newest ones I have, for reference. They look pretty similar, looks like only line numbers change, really. This has persisted all the way up to the current F18 kernel, 3.10.12-100.fc18.x86_64 . I am about to bump the system to F20, so I'll be able to see if it's still happening with 3.11 and 3.12 soon. Other reports of this often seem related to external displays, but I have no external display hooked up to the system at any point. I'm only using the internal display. By the timing, I think the traces occur during system boot and possibly shutdown.

Please boot with drm.debug=0xe, reproduce the issue and attach the complete dmesg (on the most recent kernel you have for better debug output).
Created attachment 110081 [details] dmesg with the bug Here's dmesg from a fairly fresh session, I see the kernel trace in the logs during this session so it should be fine. Kernel is 3.12.0-0.rc2.git4.2.fc21.x86_64 . I'm now in a situation where I have an external monitor connected to the laptop most of the time. It seems like when I suspend and resume, it changes the display configuration system for some reason, from span mode to clone mode.
It's exactly like the other DP wait_for_pipe_off bugs insofar that you have an eDP panel connected to the pch. That's physically the same routing as is used for external DP screens. Laptops eDP panels usually are connected to the cpu die directly and also don't seem to suffer from this issue. We don't seem to have a dupe yet here on kernel bz, but there's one on the freedesktop bugzilla at: https://bugs.freedesktop.org/show_bug.cgi?id=54687
Well, it wouldn't be a Sony if they wired it up according to the boring, _normal_ way of doing things ;)
This is still happening with kernel 3.14.0 (latest to hit Fedora 20).
Created attachment 134721 [details] dmesg on Fedora 20's 3.14.2 kernel Hi, In attach the dmesg output with drm.debug=0xe on the kernel command line. This is on a Dell Optiplex 990 with intel graphics and a Dell 30" monitor. I can reproduce this easily by simply booting the kernel with the monitor attached. There are no other GPU's in this desktop system. Let me know if there's any more info you need. Regards, Rik
Please test this patch here, should apply to any recent-ish upstream: http://patchwork.freedesktop.org/patch/24864/
doesn't apply cleanly on current Fedora 20 kernel (approx. 3.14) or Rawhide kernel (approx. 3.15rc6). just as a note, I can probably rediff it (I hope).
Welp, I just built a kernel with the patch rediffed to 3.14, booted it, and it looks like it fixes the issue for me.
(In reply to Adam Williamson from comment #10) > Welp, I just built a kernel with the patch rediffed to 3.14, booted it, and > it looks like it fixes the issue for me. Hi Adam, Can you attach your rediffed patch? I would like to check if it fixes it for me. Regards, Rik
Created attachment 137271 [details] patch rediffed for 3.14 Sure, here you go.
Created attachment 137361 [details] dmesg with the patch applied on 3.14.4 Hi, I applied the patch on Fedora's 3.14.4 kernel and still experience the WARNING. This attachment is a boot with the drm.debug=0xe parameter set. This is on on a 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) The monitor in use is a Dell U3011. Regards, Rik
I can reproduce this. The screen goes blank and does not recover. Only happens after I upgraded systemd, I can switch to sysvinit (init=/sbin/init) and I get as far as a working X session.

John-John Tedro: FWIW I'd say it's somewhat unlikely this bug is actually the cause of your boot troubles - as it's a kernel issue it would be odd for it to cause a system to fail to boot with systemd but not sysv. I suspect it's more that you're seeing some other issue with systemd boot on your distro/configuration, and you just happen to see this oops on the console when it happens. This oops at least for me is just an annoyance, it doesn't actually cause any problems with use of the system.

Certainly, I do believe the system is still 'usable' but it's preventing the only screen I've got connected to it from working, which makes it difficult to interact with. With regards to systemd; I believe you are right. But I've had a hard time nailing down what is provoking it since KMS works when I run without it. For the record; I miss systemd.
To be clear, when I say "doesn't actually cause any problems with use of the system", what I mean is that graphics work perfectly for me. I see the kernel WARNING, but there is no observable effect on actual use of the system. Graphics work, acceleration works, nothing at all visible to the user stops working. In my case.
This bug seems to be somewhat fixed since kernel 3.18-rc1. The only error still appearing is (on 3.18-rc2): [ 1.012776] [drm:intel_enable_shared_dpll] enable PCH DPLL A (active 0, on? 0) for crtc 8 [ 1.012776] [drm:intel_enable_shared_dpll] enabling PCH DPLL A [ 1.014159] [drm:edp_panel_vdd_on] Turning eDP port D VDD on [ 1.014161] [drm:wait_panel_power_cycle] Wait for panel power cycle [ 1.014306] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun [ 1.481758] [drm:wait_panel_status] mask b800000f value 00000000 status 48000001 control abcd0000 [ 1.508446] [drm:wait_panel_status] Wait complete and it is observed once during boot. I didn't see it even after X session restarts. The hardware is Sony VAIO, model VPCZ13C5E. Before kernel 3.18-rc1, tracebacks appeared on every restart of X server and sometimes during X server sessions freezing the screeen. I've been using this computer since kernel 3.14. I went back with kernel versions and the tracebacks first appeared in 3.7-rc1. I think the bug https://bugzilla.kernel.org/show_bug.cgi?id=52061 is related to this bug.

Is there still an issue with recent kernels? Yes since 3.18 backtraces are gone, except the error in comment #18. Please wait about a week with changing the status of the bug, then I'll have access to external displays and can/can't confirm that it's fixed.

For summary, after version 3.18 kernel doesn't trip any more (no segfaults). The error mentioned in comment #18 persist, but it doesn't create any inconveniences in daily use. The external monitor connection through HDMI is detected but there's no output on screen. This situation is much better than on Win7 where the driver doesn't even detect any connection. As I don't use external monitor, for me the issue is fixed. Thanks.
