[Bug 1867065] [NEW] Installer hangs at boot on machine with LVM

[Alberto Donato]

Public bug reported:

With a USB stick built from the 20200309 daily image, the installer
hangs at boot right after checking packages checksums, with an LVM-
related error.

Attached is an image of the boot screen.

Note that the "fsck:md5susms%" messages keeps repeating indefinitely.

The machine currently has dm-crypt + lvm.
