I had upgraded a desktop system with 11.4 32bit and Lenovo Laptop Z575 with 12.1 to 12.2.
Both systems have a stability issues and randomly freeze (keyboard/mouse not responding, accessing the system remotely is not possible and internal sound card starting producing a high pitch sound).
Looking the way to collect some troubleshooting information to submit a defect.
Log file /var/log/message doesn’t contain any useful information at the time of event.
Sometimes system freezes almost immediately when
- started playing music
- started watching youtube video
- accessing a web camera
However it may freeze on idle when basically no desktop application is running.
I upgraded a pulseaudio from multimedia:libs and at least accessing the web camera no longer freezes the system every time.
A note: system crashed while preparing this posting. Kudos to SuSE team with autosave feature
