I have a 2015 Acer S7 393, i5-5200U cpu, 8 Gb ram, HD5550 graphics, 2 * 64 Gb IRST kingston SSD, upgraded yesterday from 20.04.4 LTS (working fine) to 22.04 LTS.
The pc freezes after logging in (graphically, because using Ctrl+Alt+F2 on a virtual tty is ok, logging is ok, pc is working). It is with 5.15.0-48 kernel (and also with 5.4.125 old kernel, whereas 5.4.126 kernel crashes with kernel panic).
I cant 'find any hint in the logs to understand where it may come from : any hint ?
