20.04 with mdadm and lvm hangs on shutdown

cn flag

I have a server set up on 20.04 with two mdadm raids and lvm volumes put on top of those raid setups for /home on the first raid device and then /, /var and /tmp on the second raid device.

Any time I run a shutdown, reboot, poweroff or similar operation, the system runs through most of the shutdown sequence (including stopping the persistence of journal and shutdown logs) and then hangs after Shutdown[1]: Rebooting or Shutdown[1]: Powering Off. If I hit ESC, it appears to show that the unmounts of /var /tmp and / are failing, causing the raid device to fail to shutdown, though I don't know if this is causing the hang or if it's merely a coincidental, separate issue. Pictures are attached below.

I have only the intel integrated graphics and have checked the usual driver culprits. I also have updated the bios and tried various settings of acpi in grub as suggested in other answers.

What else should I be checking/providing here in order to hunt this down?

Anyone have any thoughts of even just what other logging is needed or what else I should try? I don't want to just open this as a bug and assume there's something else I can be providing here to help track things down.

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.
