journalctl -a -b

I don't know how to reproduce this, but it's been a problem on Fedora 26 as well (now running Fedora 27). The bug happens both with Wayland and Xorg. Here's the trace output:

I'll do anything I can to help debug this. There doesn't appear to be much of a way to recover in a Wayland session, but Xorg eventually seems to lock up too.

Comment 2 Jeff Peeler 2017-11-14 20:11:59 UTC 
I know the output I included contains the laptop, but this is a Lenovo P50. I have the laptop in the dock with the lid open. One external monitor is connected to the DVI port and (perhaps obviously) another external monitor is connected via DisplayPort.
Comment 3 Laura Abbott 2017-11-14 21:40:28 UTC 
Move for the graphics team to take a look.
Comment 4 Jeff Peeler 2017-11-22 18:38:10 UTC 
What additional information should I be gathering when this happens?

Comment 5 nik 2017-12-25 19:45:12 UTC 
I can reproduce a very similar crash reliably on Fedora 27.

This bug looks strongly related to https://bugs.freedesktop.org/show_bug.cgi?id=103351 and https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1723619.

The external monitor works perfectly on 4.12.9-300.fc26.x86_64 and breaks on 4.13.1-301.fc27.x86_64, the commit mentioned in that issue was introduced between these two version.

> Rob, any chance you have a kernel RPM that I could test with?

unfortunately not, I was just building kernel outside of koji/rpmbuild.  But I was having the same crash on my desktop at home without the patch.

Comment 14 Jeff Peeler 2018-01-09 00:43:37 UTC 
I recompiled a Fedora kernel with the fix made by Rob, however I'm still experiencing problems. I'm unable to boot a 4.14 based kernel with my external monitors plugged in (the problem seems to be getting worse), so I have to plug in my monitors after booting. Above I attached two dmesg outputs: one from the latest available kernel in Fedora and the second from my compiled kernel.

well, the 4.14 dmesg is at least a *different* problem.. so I guess that is progress.

My desktop at home where I had same problem (at least as what was originally reported in this bz, I haven't seen the 2nd issue you posted yet) is GF119 card, single monitor but always connected at boot.

Any chance I could get a full dmesg w/ the 4.14+patch kernel?  What you posted there is a lockdep warning.. which might be the issue you are hitting or might just be a warning about some potential issue.  IIRC the -debug kernel should have CONFIG_DETECT_HUNG_TASK=y, although I don't remember the default timeout, ie. CONFIG_DEFAULT_HUNG_TASK_TIMEOUT.. maybe 60 or 120 sec.  If you can ssh to the system after it fails to boot to login screen, if it is stuck at this point due to lock issue, then after however many seconds for HUNG_TASK_TIMEOUT you should start getting more backtraces in dmesg.  This would be useful to see.

Thanks
Comment 16 Rob Clark 2018-01-09 01:51:10 UTC 
hmm, possibly relevant.. my dp monitor is dp single stream, instead of mst.. it looks from the backtrace like yours is mst (although some monitors have a menu option to switch between mst and sst)..

from a quick look, the new issue doesn't look like something that should be a nouveau specific issue, but I'll have a closer look in the morning.

journalctl -b -k 4.15 kernel

One other data point is I tried booting a 4.15 kernel from koji. I don't see any panic, but the monitors also don't work at all.

ok, from full log, I realize that you have GM107, not GF119 and your issue is different from the backtrace that nik posted in #c5 (which is the actual issue that I fixed, but that same problem doesn't apply to GM107..
Comment 22 nik 2018-01-16 21:23:44 UTC 
Rob's patch fixed the issue for me. If anyone needs fresh RPMs built on Fedora's 4.14.13, I will try to host these until the issue is resolved:

Comment 23 Jeff Peeler 2018-01-18 16:00:00 UTC 
When will the function pointer fix be in fedora's kernel?

I'm thinking since a real issue was solved here and that my particular issue seems to vary based on the exact kernel version, I should open a new bug.

Also, I had previously considered seeing if the issue was still present with a display port to HDMI adapter, but those cost four times as much ($40) as the hdmi -> dp adapters do.
Comment 24 Jeff Peeler 2018-01-21 18:38:53 UTC 
The issue I'm experiencing is related to bug 1509294. There's also an upstream bug here: https://bugs.freedesktop.org/show_bug.cgi?id=103721. I'm going to submit further info there instead.
