** Description changed: My system has recently started hanging shortly after boot when using a kernel version newer than 5.4.0-54-generic. - I can reproduce the hanging behaviour with kernel verions 5.4.0-56-generic through 5.4.62-generic (latest at the moment). + I can reproduce the hanging behaviour with kernel versions 5.4.0-56-generic through 5.4.64-generic (latest at the moment). The system works for a few seconds but then it becomes unresponsive. It is not possible to open applications, run commands in a terminal or even shutdown anymore. Steps to reproduce: 1. Boot 2. Choose a newer kernel image 3. Login 4. In a terminal, enter sudo ls (first time works) 5. Enter sudo ls again (now hangs) Changing a to console with Ctrl+Alt+FX works shortly but then it hangs as well. - If I am quick enough I can still click on the reboot menu button but then it still hangs and cannot complete the shutdown. + If I am quick enough I can still click on the reboot menu button but then it still hangs and cannot complete the shutdown citing several stop jobs which are still running and do not complete. + Perhaps interestingly, this also creates problems with the WLAN adapter and I have no internet connection. With kernel version 5.4.0-54-generic everything works perfectly well and it has done so for years now with any previous kernel version. I would appreciate any guidance. Please feel free to ask me for further information. Thank you!
