Hi!
My Linux laptop running kernel v4.17 freezes intermittently when the laptop
lid is closed but external monitors are connected to 2 HDMI ports. I provided
details on the issue, any idea what could be causing it?
I ruled out many different subsystems by trial and error, finally I enabled
ftrace events on power subsystem and see that the freeze is precisely at the
same time as drm_mode_getconnector is called on these events and its the Xorg
process. I think since Xorg is busy on this drm_mode_getconnector ioctl, its
not able to perform its duties.
I get a stacktrace like so:
Xorg-1285 [001] .... 801.156606: pm_qos_update_request:
pm_qos_class=CPU_DMA_LATENCY value=-1
Xorg-1285 [001] .... 801.156607: pm_qos_update_target:
action=UPDATE_REQ prev_value=0 curr_value=2000000000
Xorg-1285 [001] .... 801.156609: <stack trace>
=> pm_qos_update_target
=> intel_dp_aux_xfer
=> intel_dp_aux_transfer
=> drm_dp_dpcd_access
=> drm_dp_dpcd_read
=> intel_dp_read_dpcd
=> intel_dp_detect
=> drm_helper_probe_single_connector_modes
=> drm_mode_getconnector
=> drm_ioctl_kernel
=> drm_ioctl
=> do_vfs_ioctl
=> ksys_ioctl
=> __x64_sys_ioctl
=> do_syscall_64
=> entry_SYSCALL_64_after_hwframe
The X version I'm running is X.Org X Server 1.19.6
I also see these in /var/log/Xorg.0.log every 30 seconds and it seems
correlated to the time of freezing:
[ 1141.925] (--) modeset(0): HDMI max TMDS frequency 170000KHz

Let me know if you spot anything weird, and if you have any suggestions?
thank you!

Just for documenting it, the issue seems very similar to what is reported in this comment: https://forums.linuxmint.com/viewtopic.php?t=253475#p1457587 I am indeed using Cinammon as well. With the lid closed, the same 'modeset' log messages appear and freeze the system every 30 seconds. - Joel _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel ^ permalink raw reply [flat|nested] 7+ messages in thread

Platform and panel HW would be useful to know, dmesg from boot is usually sufficient. -Chris _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel ^ permalink raw reply [flat|nested] 7+ messages in thread

So here is what I get with drm.debug=0xe. Below is a small part of it close to the "stuck" state. I do see some errors. Any insights are appreciated!

It causes an annoying Xorg hang every 30 seconds when my laptop lid is closed with external monitors connected. This is a thinkpad laptop. I am not sure how to get the panel info but if you can let me know how to do that, I can dig it out. Logs excerpts are below and full logs are attached to earlier threads.

Hi Joel, Could you please file a bug at https://bugs.freedesktop.org following: https://01.org/linuxgraphics/documentation/how-report-bugs Unfortunately the dmesg provided is not enough since it has lost the initial information. So please increase log length or capture right on the begining with only drm.debug=0xe Thanks, Rodrigo. > > On Thu, Nov 01, 2018 at 05:02:54PM -0700, Joel Fernandes wrote: > > On Mon, Oct 29, 2018 at 01:11:30PM +0000, Chris Wilson wrote: > > > Quoting Joel Fernandes (2018-10-27 09:14:07) > > > > On Sat, Oct 27, 2018 at 12:38:56AM -0700, Joel Fernandes wrote: > > > > > Hi! > > > > > My Linux laptop running kernel v4.17 freezes intermittently when the laptop > > > > > lid is closed but external monitors are connected to 2 HDMI ports.
