nouveau
The issue start to appear after upgrading to Kernel 4.9.0. Before that, on
4.8.14 everything seems to be fine.
I have Lenovo B560 laptop with Intel Core i5 560M and Iron Lake GPU, Nvidia
310M, so it's an Optimus laptop. I have external monitor connected to HDMI
port.
Components when the probelm could be reproduced:
- gentoo almost stable
- mesa 12.0.1 or 13.0.2;
- libdrm 2.4.68 or 2.4.73
- xorg 1.18.4 or 1.19.0
- intel xf86 driver snapshot or modesetting driver
- nouveau 1.0.12 or 1.0.13
- libinput 1.5.3, libevdev 1.5.2
- xfce, polkit, consolekit, dbus, etc.
So just after all services started and lightdm expected to appear with login
screen, instead I can only see console login screen and nothing appears on =
tty7
also.
Xorg.log.0 shows no errors, dmesg is also empy (even with debug level 4). I
can't reboot system after that as Xorg has red D symbol and cannot be kille=
d,
so SysRq is used.
I blacklisted nouveau driver and it helped, so I can boot to the system
normally and after that I can load the nouveau module manually and even res=
tart
Xorg.
Xorg.log.0 hangs on the following item:
[ 14.361] (II) xfree86: Adding drm device (/dev/dri/card1)
syslog kernel with nouveau filtered (only one time I enabled debug level wh=
en
the I had the problem).

Yes, kernel boots with this option. The only disadvantage is that in this c=

nvidia GPU will always stay powered on, probably could be solved with bbswi=

bbswitch won't help if nouveau is loaded.
If this is indeed a regression in 4.9, could you try and bisect this?

Well, I may need some guide or a at least some sort of explanation (probably
short) what to do as this is completely new for me. Will this guide work for
this task?

--- Comment #6 from Peter Wu ---
Nothing unusual in logs. Can you reproduce the lockup issue if you boot to a
console (disable sddm), then invoke "lspci", wait for at least 5 seconds, t=
hen
repeat "lspci" again? (Have a look at dmesg for unusual messages.)
If lspci hangs, then there is a problem (and hopefully dmesg is more helpfu=
l).
Can you also confirm that downgrading just the kernel (while keeping the re=
st
of userspace the same) makes the problem disappear?

--- Comment #7 from Gleb ---
lspci doesn't hang when I invoke it from console. I also tried startx and
startxfce4 from console and it worked, so it probably some other thing?
I can confirm that the issue occured on 4.9.0 and did not occur on 4.8.14 on
the same userspace stuff. I only started upgrading it after multiple
unseccessfull reboots into 4.9.0. So I had stable stuff, tested 4.8.14 (no
problem) and 4.9.0 (problem persist). Then upgraded stuff, tested on 4.8.14=
(no
problem) and 4.9.0 (problem persist).
I also recompiled 4.9.0 at some point before testing lspci (but not
specifically for that, I will try to revert the changes) so that it includes
nouveau into kernel and not as a module, though it still have the same issu=
e.
Does it matter in what form nouveau is presented?
I want to clarify that the only process that hangs is Xorg (and probably
another which I noticed right now -- libvirtd, it also has red D symbol). T=
he
system continue to work, I have access to console and can run stuff from th=
ere.

1st attempt: before lscpi
TL;DR `lspci` hangs on first invocation
I tried few more things, step by step:
1) removed kernel 4.9.0, modules, config, etc
2) tried 4.8.15 -- everything is fine, no hanging
3) installed 4.9.0 from scratch:
- redownloaded sources (gentoo-sources)
- copied old config from 4.8.{14,15}, so nouveau built as external module
- make silentoldconfig, for everything new I just press
- built, installed the kernel as did it before with the same steps
Conclusion:
- 4.8.14 -- OK
- 4.8.15 -- OK
- 4.9.0 -- fail (xorg hangs)
Then I tired suggested steps:
- disabled xdm, system boots to text console
- in 2nd attempt additionally disabled libvirtd
In both cases `lspci` just hangs without any output with red D status. At f=
irst
attempt libvirtd also was with red D status, at second there wasn't libvirtd
started.
Userspace stuff with for all actions was the same:
- mesa-13.0.2
- libdrm-2.4.74
- xorg-1.19.0
- xf86-video-intel (snapshot from 12 December 2016)
- xf86-video-nouveau-1.0.13
- libinput-1.5.3
- libevdev 1.5.2
dmesg attached, with "drm.debug=3D0x1e log_buf_len=3D1M", two attemps with =
2 log
files (before invoking lspci and after).

1st attempt: after lscpi
I think those logs will be enough. If necessary I can attach more, but I th=
ink
that 2nd attempt looks the same.

bisect.log
So I bisected a kernel and come to the same conclusin as in this bug

and I can move to the previous one?
