Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in Linux:
  Fix Released
Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  
  == SRU Justification ==
  A regression was introduced in Bionic.  The bug reporter states that
  the system freezes at boot, apparently when the nouveau driver tries to start.
  The console is still in 80x25 text mode at this point. No panic or error
  message is displayed, only unrelated log messages.

  This regression was introduced by commit af2405af07d168e2 in v4.14-rc1
  and fixed by the patch submitted in this SRU request.  The patch
  originated in the following upstream bug report:
  https://bugs.freedesktop.org/show_bug.cgi?id=106456

  The patch has been submitted upstream, but has not yet landed in
  linux-next or mainline.  The patch is being send as SAUCE until it lands
  upstream.

  
  == Fix ==
  UBUNTU: SAUCE: drm/nouveau: Fix deadlock in nv50_mstm_register_connector()

  == Regression Potential ==
  Low.  This is to fix an existing regression and had been sent to
  upstream stable, so it will recieve additional upstream review.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.


  == Original Bug Description ==
  After updating to linux 4.15.0-13-generic, the system freezes at boot, 
apparently when the nouveau driver tries to start.  The console is still in 
80x25 text mode at this point.  No panic or error message is displayed, only 
unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[Brad Figg]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in Linux:
  Fix Released
Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Bionic:
  Fix Committed

Bug description:
  
  == SRU Justification ==
  A regression was introduced in Bionic.  The bug reporter states that
  the system freezes at boot, apparently when the nouveau driver tries to start.
  The console is still in 80x25 text mode at this point. No panic or error
  message is displayed, only unrelated log messages.

  This regression was introduced by commit af2405af07d168e2 in v4.14-rc1
  and fixed by the patch submitted in this SRU request.  The patch
  originated in the following upstream bug report:
  https://bugs.freedesktop.org/show_bug.cgi?id=106456

  The patch has been submitted upstream, but has not yet landed in
  linux-next or mainline.  The patch is being send as SAUCE until it lands
  upstream.

  
  == Fix ==
  UBUNTU: SAUCE: drm/nouveau: Fix deadlock in nv50_mstm_register_connector()

  == Regression Potential ==
  Low.  This is to fix an existing regression and had been sent to
  upstream stable, so it will recieve additional upstream review.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.


  == Original Bug Description ==
  After updating to linux 4.15.0-13-generic, the system freezes at boot, 
apparently when the nouveau driver tries to start.  The console is still in 
80x25 text mode at this point.  No panic or error message is displayed, only 
unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[John Lindgren]

The test kernel works fine, thanks!

Ben Skeggs is an upstream nouveau maintainer, so I assume that anything
in https://github.com/skeggsb/nouveau will end up in mainline
eventually.  So I would suggest taking the patch from comment #2.  I'll
ping him on GitHub about submitting it to mainline sooner rather than
later.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[Joseph Salisbury]

It doesn't look like the patch from comment 2 landed in mainline or
linux-next as of yet.  Do you plan on submitting your patch upstream?
We could integrate either patch into the Ubuntu kernel, but we prefer to
use the one that is in the upstream kernel.


I built a test kernel with the patch from comment 2 for testing.  The test 
kernel can be downloaded from:

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Bionic:
  In Progress

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[John Lindgren]

I didn't test the patch in comment #2 directly.  It's very similar to
the one I posted in comment #1 (which I've tested), so I'm pretty
confident it would work.  I'd be happy to try out a test kernel though.

Were you able to test the fix posted in comment 2 of the upstream bug
report?  If you need, I can build you a test kernel with it.

  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[John Lindgren]

This has something to do with using DisplayPort monitors (through the
two DisplayPort connectors on the laptop dock).  When the laptop is
undocked and a single external monitor connected to the HDMI port on the
laptop itself, nouveau works fine.  Dock the laptop and suddenly it
can't boot any more.

To recap:
linux 4.13 + nouveau + 2 DisplayPort monitors = works fine
linux 4.15 + nouveau + 2 DisplayPort monitors = unbootable
linux 4.15 + proprietary driver + 2 DisplayPort monitors = works fine
linux 4.15 + nouveau + 1 HDMI monitor = works fine

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[John Lindgren]

Also affects Ubuntu Mate 18.04 Beta 2 with nouveau (using Linux 4.15).

Even the installer is unbootable unless "nomodeset xforcevesa" is added
to the kernel command line.

The proprietary NVidia driver seems to work okay.

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[John Lindgren]

I tested the following mainline packages:

linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb
linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb
linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

Still unbootable except in recovery mode.

The only difference, 4.16 generates new messages about missing firmware
that neither 4.13 nor 4.15 generated:

W: Possible missing firmware /lib/firmware/nvidia/gp108/sec2/sig.bin for module

I tried installing nouveau-firmware with no difference.

[Kernel-packages] [Bug 1763189] Re: kernel 4.15 breaks nouveau on Lenovo P50

[Joseph Salisbury]

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.
