Description Colin Williams 2016-04-20 19:22:12 UTC

On my dell latitude e5440 when I undock and redock I am unable to re-activate
both monitors using xrandr. I'm using linux kernel 4.4.5 and the i915
driver. Looking at dmesg, I found the following trace(s):

Comment 1 Colin Williams 2016-04-20 19:23:37 UTC

Just to be clear, I'm unable to re-activate both external monitors, which are attached to the docking station; only one works. Then I need to reboot to be able to do so.

Comment 2 Colin Williams 2016-04-20 23:20:33 UTC

This pertains to archlinux driver 1:2.99.917+587+gc186d4d-1 (xorg-drivers xorg) [installed] . 

There appear to be more drivers available:

https://www.archlinux.org/packages/?name=xf86-video-intel

i686	Extra	xf86-video-intel	1:2.99.917+631+gf2a4645-1	X.org Intel i810/i830/i915/945G/G965+ video drivers	2016-04-16	2016-04-17

x86_64	Testing	xf86-video-intel	1:2.99.917+636+g562ae1f-1	X.org Intel i810/i830/i915/945G/G965+ video drivers	2016-04-19	
i686	Testing	xf86-video-intel	1:2.99.917+636+g562ae1f-1	X.org Intel i810/i830/i915/945G/G965+ video drivers	2016-04-19


Then I can try the other drivers and see if the issue persists.

Comment 3 Gary Wang 2016-04-22 03:15:23 UTC

Hi Colin,
Because it's HSW platform with docking (e.g. built-in with DP-hub/display port converter...etc.), we need more information for it. 

I would like to get your help to collect some debug log for our analysis further. Please enabled drm debug in kernel message, and collect kennel command/i915 parameter/xrandr's output. Then reproduce this this issue (dock/undock) and sharing them with kernel message with us. Thanks!

1. drm debug-enabled log, 
echo 0xe > /sys/module/drm/parameters/debug
2. get kernel command
cat /proc/cmdline
3 get i915 parameters 
cat /sys/kernel/debug/dri/0/i915_display_info
tail -n +1 /sys/module/i915/parameters/*
cat /sys/kernel/debug/dri/0/i915_capabilities
4. get X's information.
xrandr -q

Comment 4 Colin Williams 2016-04-22 07:54:15 UTC

Hi Gary,

Will do ASAP.

Thanks,

Colin Williams

Comment 5 Colin Williams 2016-04-22 16:53:30 UTC

Here's 1-4 as requested. I will undock and re-dock later today, and share information.

Comment 6 Colin Williams 2016-04-22 16:56:26 UTC

By the way I also installed the most recent driver in my distribution last night, which seems to have moved out of testing.

extra/xf86-video-intel installed: 1:2.99.917+636+g562ae1f-1

Comment 7 Gary Wang 2016-04-25 08:32:41 UTC

Hi Colin, 
Please also help to upload kernel message (i.e. enable drm debug log first then reproduce issue) for our analyzing into Gfx driver. Thanks!

Comment 8 Gary Wang 2016-04-25 08:38:49 UTC

According to your information in #5, driver and X-server seems to work well for your two external monitors, right?

Does this issue go away by your updated xf86-video-intel? Thanks!

Comment 9 Colin Williams 2016-04-25 16:49:31 UTC

Hi Gary,

I updated driver and did 1-4 as described above. When I undock / dock, after your steps the system freeze / halt or panic. 

Not sure how to record any debugging information when the system halts or panics.

Not sure I can capture the logs when the system freeze halt / panics. I will try again later today.

Comment 11 Colin Williams 2016-05-03 16:58:58 UTC

Hi Gary, are you still there? I found the appropriate bug reporting instructions here:

https://01.org/linuxgraphics/documentation/how-report-bugs

Then I can follow the instructions related to the crash and will report back soon.

Comment 12 Colin Williams 2016-05-03 17:00:31 UTC

As recommended, I will create a new bug on the next crash:

Note that a new bug is preferred over adding your GPU crash dump to an already open bug. Most often the cause for the GPU hangs are different, and it is easy for the developers to mark bugs as duplicate.

Comment 13 Gary Wang 2016-05-04 02:32:23 UTC

Hi Colin, 

Yes. please refer the https://01.org/linuxgraphics/documentation/how-report-bugs for collecting log.

BTW for quickly checking, could you reproduce this issue (running "echo 0xe > /sys/module/drm/parameters/debug" prior to issue reproduction) then doing following things if not suffering system halt.

cat /sys/kernel/debug/dri/0/i915_error_state > ~/i915_error_state.log
dmesg > ~/dmesg.log

If system halted, please reboot then get "kern.log" (kernel message).

Finally, please always upload "kern.log" in folder "/var/log/" and i915_error_state.log/dmesg.log (if not system halt). Thanks!

Because I don't have your docking system, it cannot reproduce it in my side and need your detail of log further.

Comment 14 Colin Williams 2016-05-05 17:11:18 UTC

Hi Gary, I was able to get the log! Since I'm using systemd, the kernel logs are found in journald. First the panic:

I saw gpu hung then got drm_kms_helper's kernel panic in you built kernel 4.4.5/i915 driver, but still could not get the whole picture of this issue due to lacking context of full log.

What kind of OS (e.g. Ubuntu/version, Dell's enterprise Ubuntu system...etc.) do you use for this issue? We need concrete information for analyzing it. 

Could you please try the latest Ubuntu system like 15.04/16.04 to verify this issue then upload collected log for our analyzing further? Please also use the latest drm-intel-nightly to verify issue again.

We don't have your Dell docking system and cannot do analysis directly but only based on your provided information.

Comment 17 Leon Romanovsky 2016-07-06 05:42:58 UTC

Hi,

I wanted to update that the same behaviour as described occurs to me with Lenovo x250 notebook connected to Lenovo docking station.

I'm running Ubuntu with kernel - 3.19.0-58-generic.

From dmesg, after dock event:

Comment 18 Leon Romanovsky 2016-07-31 04:51:46 UTC

As a workaround, I'm using the following script to force activation of monitors.

cat ~/.screenlayout/two-dock-force.sh
#!/bin/sh

Comment 19 Jani Nikula 2017-05-11 08:12:17 UTC

Please upgrade to v4.11, and if the problem is still reproducible, please add drm.debug=14 module parameter, and attach dmesg all the way from boot to reproducing the problem. (See the "Add an attachment" link near the top; adding logs as comments makes the bugs hard to read.)

Hello Leon,
Is this bug still valid with the latest kernel on your case? If so, please share the information requested to proceed. Thank you.

I'm not experiencing those problems with v4.11.5 (stable) anymore.

Thanks
