Title:
  System doesn't boot (root device never becomes available after
  entering encryption passphrase) after today's Hirsute updates

Status in lvm2 package in Ubuntu:
  Confirmed

Bug description:
  Note: I'm guessing that lvm2 is the most likely culprit for this
  issue, but I don't know for certain.

  After today's Hirsute upgrades, my system won't boot. The boot gets to
  the point where it asks me for the passphrase for my encrypted root
  disk, and I enter it, and then it says that it was unlocked
  successfully, and then it spins for a while, and then I get the
  message shown in the attached photo.

  When I reboot with the older pre-Hirsute kernel (5.8.0-43-generic) I
  have installed the system boots successfully, but I don't think this
  is a kernel issue per se since I didn't upgrade the kernel today and
  my system has rebooted successfully before with the Hirsute kernel I
  currently have installed.

  Note: the two kernel messages shown at the beginning of the photo are
  not relevant; they occur even when I fall back to the old kernel and
  boot successfully.

  Attached: photo of console from failed boot, list of packages that
  were upgraded today.
