Bug ID: 493093
Summary: cpu plugin causes hang/crash when starting
plasma-ksystemstats daemon
Classification: Frameworks and Libraries
Product: ksystemstats
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: General
Assignee: plasma-b...@kde.org
Reporter: jhanm...@ca.rr.com
CC: ahiems...@heimr.nl
Target Milestone: ---
SUMMARY
The ksystemstats daemon will not start on my Rock-5b system. It is running the
Armbian vendor kernel version 6.1.75. The very latest version. I am running Qt
6.7.2 with the latest build of the Plasma 6 tips.
By process of elimination I determined that if I prevent loading of the cpu
plugin (by renaming it to .no instead of .so) the daemon will load and operate
correctly albeit without cpu stats present. There is no output message in
either the systemd journal or the system log (dmesg) so I can't currently offer
more information on what may be going wrong. I'm going to try to look at the
plugin code to see if I can spot anything.
Of course if I can provide any more information you need only request it.
STEPS TO REPRODUCE
1. Build ksystemstats
2. Try to start with systemctl --user start plasma-ksystemstats
3. Timeout after a few minutes but no messages other than the timeout
indication.
