edit: Sysrq key is Print Screen for those who didn't know

edit2: hardly anyone has a keyboard with a Print Screen button anymore though]]>https://board.circlewithadot.net/post/https://friedcheese.us/objects/807412af-4c79-4f8a-b6db-f0b9efc377e2https://board.circlewithadot.net/post/https://friedcheese.us/objects/807412af-4c79-4f8a-b6db-f0b9efc377e2Fri, 15 May 2026 17:43:51 GMT<![CDATA[Reply to How to force reboot a frozen Linux or FreeBSD machine on Fri, 15 May 2026 17:39:42 GMT]]>@kirby ahahah that's funny!

"… more likely to happen when dealing with usb attached external interfaces. …"

On the many occasions when I have lost then regained USB connectivity to a mobile hard disk drive that hosts a ZFS pool, and (naturally) it becomes impossible to run any zpool command on the pool:

– there's never an endless freeze.

Restart the OS in the normal way, and be patient. Sometimes very patient.

That was, Kubuntu 25.04 and 25.10 with (OpenZFS-encrypted) root-on-ZFS. I have not yet had an opportunity to play the waiting game with 26.04.
