Ok I upgraded from Linuxmint 20.1 to 20.2 yesterday and everything went smooth. But unfortunately the freeze is back. This time, the system rebooted automatically, so no hard freeze. On startup I got the following error on screen short before the OS boots:

But I cannot get any conclusion from this other than there is something wrong with the CPU. Is this related to the kernel then and is this here the right place to post this? If no, where could I look for more information on this? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1913933 Title: System freeze while dbus-daemon execution Status in linux package in Ubuntu: Confirmed Bug description: I regularly get my system frozen while using.
