Dmesg from system start until and including the second time a kernel backtrace
appears

I was referred by my distributions bug tracking to report an error related to
the Nouveau drivers here.

I use the "Tumbleweed" distribution by Opensuse. This is a kind of
rolling
release with package upgrades circa once a week. On 2015-11-08 I pulled that
distributions latest snapshot, which installed among not many other packages
Linux kernel version 4.3.0, which was an upgrade from 4.2.4.

Since then I experience grave issues when using the KDE desktop. Beginning on
that Sunday (i.e. 2015-11-08) after some time of using the desktop I noticed
that KDEs text editor ("Kwrite") would not start anymore when launched
from the
file manager. Initially I thought this was an communcation problem inside KDE,
because I could restart the file manager and managed to open one text file. But
then, attempting to launch a second instance of Kwrite via the file mananger
failed again. I tried repeatedly and found that after very few attempts Kwrite
could not be launched anymore. At that time I could still interact with other,
running programs. But after some time the whole desktop locked up. Not even
switchting to a text console via Ctrl + F1 worked. The system had to be
rebooted.

I can now reproduce a whole desktop lockup by this simple procedure:

- Power on
- Login in KDM
- Pressing Alt + F2, then typing konsole in the mini command line
- Entering dmesg in Konsole window.
- Opening a second Konsole tab.
- In that new tab, typing kwrite. Kwrite is not launched successfully by that
attempt.


To gather information, I installed kernel version 4.2.4 from the distributions
package in parallel to 4.3.0.

When I boot 4.2.4, I can not reproduce the desktop lockups.

I have attached the complete dmesg output which stems from the procedure to
reproduce above. As you can see, there are some suspicious kernel backtraces
related to Nouveau. One of these backtraces is associated in time closely to
attempting to launch Kwrite, i.e. after I type "dmesg" for the first
time I
only see one backtrace. Then, after entering kwrite I can request dmesg again
and spot the second kernel backtrace.

With slightly older kernel versions I also get these kernel backtraces in the
system log (journalctl), but I do NOT experience whole desktop lockups. With
even older kernel versions, I do not get these types of kernel backtraces. 
These are the lines from when journactl indicates a similar backtrace for the
first time: (The installed kernel must have been 4.2.3 as far as I can
determine through inspecting the package install history logfile.)

For your information I have attached files showing the package install history
(only the most recent weeks), output of "hwinfo --gfx" and a bit of
information
about installed packages (I hope you can make something out of the RPM output,
if not I am glad to supply any missing information). Of course I attached the
dmesg output as well, as written above.

For reference I opened this report in Opensuses bug tracking:
https://bugzilla.opensuse.org/show_bug.cgi?id=954473

For further information, for some time now (ca. since mid 2015) I also get
similar Nouveau failure message to those that are attached here:
https://bugs.freedesktop.org/show_bug.cgi?id=92504
But these do not usually provoke hard desktop lockups, and are only seen when I
also use Firefox, which I do sparingly. So that is likely a separate problem,
which has a weak relation to my recent troubles.

Nouveau underwent a significant rewrite for kernel 4.3. Any chance you could
bisect the changes to drivers/gpu/drm/nouveau between v4.2 and v4.3?

I will try to bisect between 4.2 and 4.3. I will likely not report back until
the weekend. Thanks for answering so fast.

--- Comment #6 from Andreas Nordal <andreas_nordal_4 at hotmail.com> ---
I believe I'm seeing the same bug:
* plasma5 hangs with kernel to 4.3, but not 4.2
* "resource sanity check" in /var/log/messages

I have an "NVIDIA Corporation G98 [Quadro NVS 295] (rev a1)" as seen
by lspci
(Dell workstation).

I have kernel-default-4.3.0-2.1 on Tumbleweed, but when I had
kernel-default-4.3.0-1.1, I was also seeing "DRM: GPU lockup - switching to
software fbcon" like in #92971.

I have a very similar setup.
- OpenSUSE Tumbleweed
- Dell Laptop (E6510)
- NVIDIA Corporation GT218M [NVS 3100M]
- upgraded kernel to 4.3.0


And exactly the same symptoms
(down to the same call backtrace).


Thus, I can help testing driver fixes if needed.

Also @Volker Lukas:
- Where did you get the older still functioning copy (4.2.4 ?)
I would like download and have until the 4.3.0 kernel gets fixed, but all the
tumbleweed mirror seem to have deleted the older kernel RPMs and only have the
latest one.

Hi doktor.yak,

at the time I encountered this bug, the Opensuse Linux 4.2.4 RPM was still
downloadable.

If you build linux-4.2.6.tar.xz from kernel.org via "make rpm" you
should be
able to get a working kernel package. You can copy the
/boot/config-4.x-something to the kernel source directory to copy the build
configuration (rename it to ".config").

Thanks for your answer.

Do you know if Suse did apply any patch on their version of the 4.2.4 kernel ?

Otherwise I'll follow your recommendation and compile a vanilla kernel.
(with
"make oldconfig"-ing /proc/config.gz)

Nothing about nouveau.

It's anyway better to compile by yourself for excluding any subtle
differences.

With current Opensuse snapshots this problem is gone apparently. One notable
upgrade is that of Linux to 4.4.0, but other upgrades also happened to
X-Server, Mesa, KDE, Qt, etc...
