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.

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.

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

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.

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.

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:
http://kernel.ubuntu.com/~jsalisbury/lp1763189

Can you test this kernel and see if it resolves this bug?

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.

Thanks for testing! I"ll submit an SRU request for that patch.

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!
