Bug ID: 401350
Summary: kwin_wayland randomly segfault on
libKF5WaylandServer.so.5.50.0
Product: kwin
Version: 5.13.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: koali...@gmail.com
Target Milestone: ---
SUMMARY
I recently migrated my gentoo to a ryzen 7 laptop, after
rebuilding full system I randomly keep having freezes that
forces me to reboot the machine by the power button. From
/var/log/messages I can read the following lines:
Nov 23 14:50:32 bee kernel: kwin_wayland[18524]: segfault at 10 ip
00007f8e44b63e90 sp 00007ffdbeb60218 error 4 in
libKF5WaylandServer.so.5.50.0[7f8e44afc000+ee000]
Nov 23 14:50:32 bee kernel: Code: 48 3b 78 10 74 c4 49 83 c0 08 49 8b 00 48 3b
78 10 75 9a eb b5 4c 8d 42 18 eb af 90 0f 1f 40 00 66 2e 0f 1f 84 00 00 00 00
00 <48> 8b 47 10 c3 90 66 2e 0f 1f 84 00 00 00 00 00 41 55 41 54 49 89
STEPS TO REPRODUCE
1. Start plasma, and run normal desktop tasks, specially if they consume
loads of memory like chromium, firefox, and akonadiserver.
OBSERVED RESULT
Full laptop freezes having easily more than half of the swap yet available.
EXPECTED RESULT
Run without freezes until swap memory gets full.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo stable plasma ebuilds.
(available in About System)
KDE Plasma Version: 5.13.5
KDE Frameworks Version: 5.50.0
Qt Version: 5.11.1-r1
ADDITIONAL INFORMATION
I'm not really familiar with debugging/providing better traces for
kwin_wayland, but I'm willing to help if guidance is offered, and spend time
looking at documentation to learn, so any help would be greatly appreciated.
Thanks!
José.
