Title:
[radeon] sumo2 locks up and fails to train displayport during boot
(panel turns off)
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Problem: Laptop panel turns off during boot, which makes the laptop
unusable.
Expected Results: Laptop panel is ON when I boot without "nomodeset",
and I can use graphical UI.
Guys from #radeon channel on "irc.freenode.net" said:
<chithead> radeon 0000:00:01.0 is the sumo2 and it locks up
<chithead> radeon 0000:01:00.0 is the caicos but there seems to be no problem
with it
<airlied> the problem is the sumo crashing and failing to train displayport
<airlied> as it's the travis bridge it's trying to modeset which is the panel
<airlied> fixing the travis bridge is the first problem
I also tried the latest (v4.7-rc3) manually installed kernel,
confirmed that the bug remains, and submitted the bug here
https://bugs.freedesktop.org/show_bug.cgi?id=96527 .
WORKAORUND: Use kernel parameter nomodeset when booting. UI works with
this kernel parameter but it's not usable as it's very slow.
