I took at least 18 hours uptime (usually 24 hours) as a sign for good
kernels.  During the bisection, bad kernels hung after 3 h, 2 h, 9 min,
45 min, and 4 min uptime.  Thus I arrived at a98ee79317b4 "drm/i915/fbc:
enable FBC by default on HSW and BDW" as the point where the hangs are
introduced.

Quoting the changelog of the commit:

    Oh, and in case you - the person reading this commit message - found
    this commit through git bisect, please do the following:
     - Check your dmesg and see if there are error messages mentioning
       underruns around the time your problem started happening.

Well, I always had the followings lines in dmesg:
[drm:intel_set_cpu_fifo_underrun_reporting] *ERROR* uncleared fifo underrun on pipe A
[drm:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe A FIFO underrun

I always got these when I switch on the DisplayPort attached monitor.
Recently I changed userland from kdm to sddm and noticed that I
apparently get these when sddm shuts down.  I am not aware of whether
or not this also already happened with kdm.

However, "around the time your problem started happening" there is
nothing in dmesg, because "your problem" is a complete hang without
possibility of disk IO and without netconsole output.

     - Download intel-gpu-tools, compile it, and run:
       $ sudo ./tests/kms_frontbuffer_tracking --run-subtest '*fbc-*' 2>&1 | tee fbc.txt
       Then send us the fbc.txt file, especially if you get a failure.
       This will really maximize your chances of getting the bug fixed
       quickly.

Do you need this while FBC is enabled, or can I run it while FBC is
disabled?

     - Try to find a reliable way to reproduce the problem, and tell us.

The reliable way is to just wait for the kernel to hang after about
3 minutes to 5.5 hours.  I have not identified any special activity
which would trigger the hang.

     - Boot with drm.debug=0xe, reproduce the problem, then send us the
       dmesg file.

I can try this, but I am skeptical about getting any useful kernel
messages from before the hang.

PS:
I am mentioning the following just in case that it has any relationship
with the FBC related kernel freezes.  Maybe it doesn't...  There is
another recent regression on this PC, but I have not yet figured out
whether it was introduced by any particular kernel version.  The
regression is:  When switching from X11 to text console by [Ctrl][Alt][Fx]
or by shutting down sddm, I often only get a blank screen.  I suspect
that this regression was introduced when I replaced kdm by sddm, but
I am not sure about that.

Oh, well... I had a patch that would just disable FBC in case we saw a
FIFO underrun, but it was rejected. Maybe this is the time to think
about it again? Otherwise, I can't think of much besides disabling FBC
on HSW until all the underruns and watermarks regressions are fixed
forever.

FBC enabled. Considering your description, my hope is that maybe some
specific subtest will be able to hang your machine, so testing this
again will require only running the specific subtest instead of waiting
18 hours.

Maybe there is some relationship, since this operation involves a mode
change. You can also try checking dmesg to see if there are underruns
right when you do the change.


If you don't want to keep carrying a manual revert, you can just boot
with i915.enable_fbc=0 for now (or write a /etc/modprobe.d file). Also,
it would be good to know in case you still somehow see the machine
hangs even with FBC disabled.

Thanks,
Paulo

Hm, if it's watermarks then testing with latest drm-intel-nightly would be
interesting. We finally managed to land atomic watermark updates (should
all be there in 4.7 too):

Just to be clear though, I know that these messages are emitted when the
monitor is switched on, and when sddm is being shut down --- but I do not
know whether there is any sort of underrun when I get the FBC related
freeze (since I just don't get any kernel messages at that point).

Is there a chance that a serial console would fare better than
netconsole?  This board and another PC in its vicinity have got onboard
serial ports but I don't have cables at the moment.

The kms_frontbuffer_tracking runs from which I posted output two hours
ago did not trigger a lockup.

(I ran them while X11 was shut down because otherwise
kms_frontbuffer_tracking would skip all tests with "Can't become DRM
master, please check if no other DRM client is running.")

Yes, this is accompanied by

[drm:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe A FIFO underrun

The fact that underruns have occurred earlier is enough to know that
something is wrong (most probably, bad watermarks): we stop reporting
underruns once we get the first one. In addition, we already know that
FBC has the tendency to amplify apparently-harmless FIFO underruns into
black screens, and I wouldn't be surprised to learn that it could also
cause full machine lockups.

In the past, for some specific cases not related to FBC, I had more
luck with serial console than with netconsole. But if this is really
caused by FBC and watermarks, I don't think you'll be able to grab any
specific message at the time of the machine hang. OTOH, if something
actually shows up, it could help invalidate our current assumption of
the relationship between the problem and FBC and underruns.

Yes, this is the correct way.

As expected, i915.enable_fbc=0 works fine.
No freeze within 2.5 days uptime; tested on v4.6-rc6.

Furthermore, I checked out drm-intel.git (v4.6-rc6-962-g91567024d358
"drm-intel-nightly: 2016y-05m-06d-14h-29m-58s UTC integration manifest")
and applied "git diff v4.6-rc6..." on top of v4.6-rc6.

I booted the result once with default i915.enable_fbc, i.e. FBC enabled,
performed the test which Daniel asked for (I will post the results in
another message), then started X11.
  - The good news:  I was able to switch back and forth between the sddm
    greeter screen on tty7, the text consoles at tty1...6, and the logger
    at tty12 --- without getting any FIFO underrun messages and without
    getting stuck with a blank screen.
  - The bad news:  Less than a minute after login into sddm, just after
    having started openbox + lxpanel + konsole, the kernel froze again
    without netconsole output.

I am now on 4.6.0-rc6+intel-drm-nightly with i915.enable_fbc=0.  This is
running fine so far.  (uptime is just 30 minutes now though, so that
doesn't say a lot.)  Again, switching between ttys works without FIFO
underruns, unlike plain v4.6-rc6.  Not sure if it is coincidence or if
this is because somebody fixed something.

Like v4.6-rc6 and older,4.6.0-rc6+intel-drm-nightly still exhibits the
following behaviour:  If I switch the displayport connected monitor off
and on again, the following messages are logged when the monitor comes on:
    [drm:intel_set_cpu_fifo_underrun_reporting] *ERROR* uncleared fifo underrun on pipe A
    [drm:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe A FIFO underrun
Other than these messages, there is nothing extraordinary going on.

I booted 4.6-rc5 with drm.debug=0xe.  It hung after about 80 minutes
uptime, and just like at all previous hangs, netconsole did not capture
anything at the time when it froze.

Here is "dmesg | grep -e 0000:00:02.0 -e i915 -e drm" from that session.

This one failed in both runs. Can you please retest with just that using

# kms_frontbuffer_tracking --run-subtest fbc-1p-primscrn-spr-indfb-fullscreen

Also please boot with drm.debug=0xe and grab the full dmesg of just that
single subtest. There's definitely something going wrong here.

I performed this test with
  - plain v4.6-rc6,
  - v4.6-rc6 patched with drm-intel-nightly (2016y-05m-06d-14h-29m-58s).

On v4.6-rc6, the test failed thus:

-------- 8< --------
Subtest fbc-1p-primscrn-spr-indfb-fullscreen failed.
