Looking at this bug for the umpteent time, I would suggest closing this one, RESOLVED WESUCK, and starting with a clean slate by filing a new bug against v4.0-rc1 or drm-intel-nightly. There's too much baggage here for anyone to look at this with fresh eyes, or if they were fresh while starting they won't be fresh by comment #136. The new bug can reference this one for historical perspective, but I think it would be best to narrow it down to describing the symptoms running the new kernels only.

(In reply to comment #115) > Yes, it works. Thanks, it narrows it down. I looked through the Intel HW IOMMU code and haven't found anything obvious that could explain this. OTOH, looking again at the dmesg with the crash (dmesg-3.10.0-rc6-00406-g73bc88c) I can't see the HW IOMMU being enabled. I'd expect "PCI-DMA: Intel(R) Virtualization Technology for Directed I/O". Instead I see SWIOTLB being enabled there. But if you are using SWIOTLB I don't understand why igfx_off makes any difference. Also the workaround in my patch should be already active for SWIOTLB, so that shouldn't make any difference either.

This bug seems to be fixed for me on raring for Zenboox UX31E (sandy bridge). Earlier I didn't notice the bug at all since I only rarely used external monitor.

I think I've hit basically the same problem Oleksij is reporting (blank eDP) when using the ASUS UX31E with an external HDMI monitor and leaving it plugged in while booting (https://bugzilla.redhat.com/show_bug.cgi?id=844985). Aside from the fact Oleksij uses VGA and I use HDMI, it otherwise seems to be the same issue.

Some clues as to which may not be zero may be found in: commit f01eca2e52169eaf3a485cbd9752435489fbfba9 Author: Keith Packard Date: Wed Sep 28 16:48:10 2011 -0700 drm/i915: Correct eDP panel power sequencing delay computations Store the panel power sequencing delays in the dp private structure, rather than the global device structure. Who knows, maybe we'll get more than one eDP device in the future. From the eDP spec, we need the following numbers: T1 + T3Power on to Aux Channel operation (panel_power_up_delay) This marks how long it takes the panel to boot up and get ready to receive aux channel communications. T8 Video signal to backlight on (backlight_on_delay) Once a valid video signal is being sent to the device, it can take a while before the panel is actuall showing useful data. This delay allows the panel to get something reasonable up before the backlight is turned on. T9 Backlight off to video off (backlight_off_delay) Turning the backlight off can take a moment, so this delay makes sure there is still valid video data on the screen. T10Video off to power off (panel_power_down_delay) Presumably this delay allows the panel to perform an orderly shutdown of the display. T11 + T12 Power off to power on (panel_power_cycle_delay) So, once you turn the panel off, you have to wait a while before you can turn it back on. This delay is usually the longest in the entire sequence. Neither the VBIOS source code nor the hardware documentation has a clear mapping between the delay values they provide and those required by the eDP spec. The VBIOS code actually uses two different labels for the delay values in the five words of the relevant VBT table. MORE LATER *** Look at both the current hardware register settings and the VBT specified panel power sequencing timings. Use the maximum of the two delays, to make sure things work reliably. If there is no VBT data, then those values will be initialized to zero, so we'll just use the values as programmed in the hardware. Note that the BIOS just fetches delays from the VBT table to place in the hardware registers, so we should get the same values from both places, except for rounding. VBT doesn't provide any values for T1 or T2, so we'll always just use the hardware value for that. The panel power up delay is thus T1 + T2 + T3, which should be sufficient in all cases. The panel power down delay is T1 + T2 + T12, using T1+T2 as a proxy for T11, which isn't available anywhere. For the backlight delays, the eDP spec says T6 + T8 is the delay from the end of link training to backlight on and T9 is the delay from backlight off until video off. The hardware provides a 'backlight on' delay, which I'm taking to be T6 + T8 while the VBT provides something called 'T7', which I'm assuming is s On the macbook air I'm testing with, this yields a power-up delay of over 200ms and a power-down delay of over 600ms. It all works now, but we're frobbing these power controls several times during mode setting, making the whole process take an awfully long time.
