Raven Ridge Ryzen 2500U hang reproduced

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Nicolai,

It makes sense.

The easiest way to reproduce the real freeze is to:
- Run vblank_mode=0 glxgears
- Open https://hangouts.google.com/start
- Activate KDE compositing

It will freeze within a few minutes.

Cheers,
Bráulio
