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.
