Ubuntu 22.04 stops in kworker

kp flag

After running Ubuntu 22.04 for a few hours, it crashes. It crashes completely and requires a physical reboot. When this happens, the first process on top is kworker, as shown in the image:

kworker itself is unlikely to be the culprit. You may find something useful at the bottom of `journalctl -b -1`. Which is the previous boot (change the -1 to -2 for the previous before that etc). Perhaps there was an error captured there? Has the system really locked up? When it next does this, try ALT-SysRQ then with ALT still pressed, press S (sync). If the disk like blinks, the kernel is still alive, and not hard-locked.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
