Screen goes black and becomes unresponsive after upgrade from 21.04 to 21.10

From time to time, the screen goes black and becomes unresponsive. Force restarting or closing the lid to put the computer to sleep fixes the problem. I recently upgraded from Ubuntu 21.04 to 21.10 using the Software Updater. This problem was not present in 21.04 although I don't remember the kernel / drivers used in the old build.

I cannot reproduce the crash although it happens almost hourly with constant usage. The messages in /var/log/syslog are inconsistent between different crashes. Once the following message appeared before a crash

kernel: [22239.387729] i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun

this error also appears in dmesg.

I followed the advice in

https://bbs.archlinux.org/viewtopic.php?id=263720

adding

intel_idle.max_cstate=4

in the kernel commandline but it did not fix the problem.

lspci -v | grep VGA

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.
