Hi,

tested next-20150202. System boots, but graphic output is broken (empty black screen).
Booted five times the same kernel, always got the same result. The system works with 3.19-rc7.

This is the first warning in the log: 

 WARNING: CPU: 0 PID: 855 at drivers/gpu/drm/i915/intel_uncore.c:169 intel_uncore_forcewake_reset+0x188/0x24d [i915]()

Those two warnings are more or less symptoms of the black screen (well
the first is just overzealous). More important would be the drm.debug=6
dmesg from boot along with the gdm.log (or equivalent) aned Xorg.0.log
as my guess is that X (or the display server) is crashing.

Requested logs with drm.debug=6 are attached. lightdm was running after WARN_ON, but I couldn't restart it.
The command hanged.

As I booted next-20150202 system crashed several times with a lot of drm_ calls in the backtrace, but I couldn't catch kernel logs,
because I have not serial port on the laptop.

If you need to get other information or to test patches, I would be glad to help.

Hi, 

This warning is moved from linux-next to v4.0-rc1 now. After system boot is just a black screen.
I ssh'ed into the machine and saved the log. I attached updated dmesg.log with drm.debug=6. Hopefully it helps. 
If you need any other debug information, traces, core dump or something else. Feel free to ask.

Hi, 

This warning is moved from linux-next to v4.0-rc1 now. After system boot is just a black screen.
I ssh'ed into the machine and saved the log. I attached updated dmesg.log with drm.debug=6. Hopefully it helps. 
If you need any other debug information, traces, core dump or something else. Feel free to ask.

Sorry, forgot to attach log to the previous mail.

The warning from free_object is annoying (and quite possibly dangerous),
but the actual hang during boot is:

i.e. it is a mutex deadlock inside tv detect. Daniel does that make sense?

Botch locking rework for atomic. Fix is

https://patchwork.kernel.org/patch/5861631/

and will land as soon as an affected user has provided a tested-by.
Andrey, can you pls give this a spin?

Thanks, Daniel

Hi,

Tested-by: Andrey Skvortsov <andrej.skvortzov@gmail.com>

The patch certainly fixes deadlock and Xorg is running again.


Unfortunately this is not the last bug, that breaks i915/drm working
on my laptop. Sometimes system successfully loads with couple warnings mentioned in
previous mail:

[   26.922953] WARNING: CPU: 1 PID: 767 at drivers/gpu/drm/i915/i915_gem.c:4525 i915_gem_free_object+0x13f/0x288 [i915]()

and

[   36.794045] WARNING: CPU: 0 PID: 18 at include/linux/kref.h:47 drm_framebuffer_reference+0x60/0x6b [drm]()

but pretty often kernel crashes during a boot. I caught the kernel log
over netconsole.

According to the backtrace this looks like a drm regression. The full
kernel log with drm.debug=6 is attached. It was taken from v4.0-rc1

That's inocuous, but for the serious hang, you may want to try
video=SVIDEO-1:d on the kernel commandline to workaround the hang. (Check
/sys/class/drm/card/ for the actual name of the connector for TV). I
think Ville mentioned he was looking/looked at the atomic-vs-load_detect
changes that is at the heart of the issue here. (Admittedly he did say
it was worthy of a drink or two.)

Thank you for the help. I've tried to add to the kernel command line
'video=card0-SVIDEO-1:d video=card0-VGA-1:d'. But despite of that
kernel crashes with 'BUG: unable to handle kernel NULL pointer
dereference at' occasionally.

Remove the card0- and combine both into a single video= stanza:
video=SVIDEO-1:d,VGA-1:d

I've just tried that, but the crash with NULL pointer dereference still happens.

Drat. In hindsight it should have been obvious since the crash is from
the driver probing the hardware during init and not the runtime output
detection. :|

I'm hitting this exact same warning on one of my test boxes.

It's not connected to a monitor so I don't know if it has a blank screen or not.
But because of the warning, it makes my tests fail (ktest fails or call traces
like this).

I bisected it down to this commit:

commit 455a68086d1dfb801ad7c867d5ca0ed0e0f758b0

    drm/i915: remove intel_pipe_set_base() (v4)

Any movement on this? I still get this warning on 4.0-rc4.

Sorry for not looking into this, I've thought we've addressed this already
and the fix is simply still in-flight to 4.0-rc. Seems it's not :(

Is linux-next also affected or is this just a case of i915 maintainers
having failed to push the right patch to -fixes?

I'll try to figure out what fell apart here meanwhile. To help out, can
you please boot with drm.debug=0xe and grab the full dmesg for booting?
Looks like it falls over in the initial fbcon modeset, which is indeed
strange ...

Thanks, Daniel

I just confirmed, linux-next boots without the warning.

The unnerving part is that I didn't find any patch not anything else that
might fix this frontbuffer_bits leak. I also couldn't spot the bug.

The real reason why -next works and 4.0 doesn't seems to be that 4.0
reconstructs a bogus initial framebuffer and then falls over when cleaning
that up. -next just doesn't reconstruct that framebuffer and hence also
can't fall over on cleanup.

Can you please cherry pick 42a7b088127f (\"drm/i915: Make sure the primary
plane is enabled before reading out the fb state\") from -next to 4.0-rc
to test whether this is indeed the difference in ducttape?

Thanks, Daniel

I cherry-picked that patch and the warning does go away.

Cherry-picked to drm-intel-fixes to queue it to v4.0-rc. Thanks for the
report and testing.
