[ 0.232774] smpboot: CPU0: AMD Ryzen 5 4500U with Radeon Graphics (family: 0x17, model: 0x60, stepping: 0x1) for the other laptops
When i switch back to a LM-image from December 2021 the problem is gone. After installing all updates the problem is back. Update to Kernel 5.13.0-28 from yesterday didn't fix.
Problem is fixed With the patches from the last 23 days i'm not able to reproduce the problem now. Thanks to all humans who give code to fix this problem.
Issue The internal monitor only shows black/white flickering points (no picture).

Other information Reproduceable on 15 laptops from my school on LM 20.1, 20.2 and 20.3. My colleague installed latest ubuntu on one of the laptops and the problem could not be reproduced.
