Bug 104806

Created attachment 136988 [details]
bt-full.txt

I can confirm lots of KDE apps and even QT only crash after upgrading to mesa 18.0.0-rc2. This is a stacktrace from qupzilla, a qt browser. Attached is the same stacktrace but generated with `bt full` so it also shows local variables.

Core was generated by `/usr/bin/qupzilla -session 10ddca7665000151644676500000008200015_1516586983_963'.

Also gentoo, also radeon card (r600).

Posting this just to confirm there is an issue. Can't provide additional info because I needed to restore access to my PC as fast as possible.

dmesg pointed segfaults in plasmashell and sddm-helper processes.
First I thought it is somehow related to updating kernel 4.14.12->4.14.15, but reverting it did not help.

Then, I saw mentions of r600g_dri.so
Switched from mesa-18.0.0-rc2 to mesa-17.3.3, and issue is gone.

I think this might be a duplicate of Bug 104762, which is fixed in master

Does deleting the shader caches work around the issue for you?

Well, after deleting the caches I couldn't get to the point where everything crashes since SDDM only shows blank white screen and standard black X11 mouse pointer instead of welcome screen.
No interesting error messages were recorded in log.

As always, thing were back to normal after I downgraded Mesa again.

Out of interest does the issue show up if you use the 9999 ebuild? If that still shows issues try bisecting the problem

9999 looks good.

Hopefully sorted in rc3 then

I run into this issue with 18.0.0_rc3, radeonsi on amdgpu with dc:

Application: krunner (5.11.5)

Qt Version: 5.9.3
Frameworks Version: 5.42.0
Operating System: Linux 4.15.0-gentoo x86_64
Distribution: "Gentoo Base System release 2.4.1"

-- Information about the crash:
- What I was doing when the application crashed:

I pressed Alt+Space, KRunner showed up briefly, but immediately crashed thereafter.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

It appears that over time more and more applications get 'infected': KWin and JetBrains Toolbox now also cannot start anymore.

I tried:
rm -fr ~/.cache/mesa

But that still does not allow me to start e.g. KRunner or KMail.


I managed to restart KWin from a VT, though, so that one might be affected in a different way.


Sadly the stacktraces of KWin and JetBrains toolbox are not as helpful as that of KRunner:

I will rebuild KWin with debug symbols and try to repro afterwards, to get a better stack trace.

When running glxinfo, I also noticed the following output on stderr:
amdgpu_parse_asic_ids: Cannot parse ASIC IDs: Resource temporarily unavailable

Created attachment 137048 [details]

With DRI_PRIME=1, I do not see 'Resource temporarily unavailable' on stderr.

That commit is not in any released version of libdrm. Please do a release containing it.

It'll be in the next release. I don't see the need to cut a release specifically for such a cosmetic issue, but feel free to do it if you disagree. :)
