partition detection breaks after upgrade to 22.04

[Daniel Golle]

After upgrade to 22.04 the partitions on the fakeraid (Intel Storage Matrix) device mapper node are no longer detected by the initramfs. This results in the system hanging waiting for the LUKS encrypted device is a partition on the fakeraid array, containing LVM2 volumes for rootfs and swap/hibernate.

When being dropped into (initramfs) busybox I can get the system to boot by running:

kpartx -a /dev/mapper/${longnameoffakeraidvolume}
cryptsetup luksOpen /dev/mapper/${longnameoffakeraidvolume}3
lvm pvs
lvm vgs
lvm lvs
lvm lvchange -a y ubuntuvg
exit

Ironically the system then asks me again to enter the password even though the volume has already been unlocked.

I suppose that a call to 'kpartx' is missing somewhere in the script-hooks for the initramfs.

The problem is also being discussed here:

Are you able to get logs from the failed boot with journalctl? If so can you add them to this bug?

[Daniel Golle (dangowrt)]

Unfortunately `jounrnalctl` is not available yet early in (initramfs) busybox.
Or do you mean log output once the system has fully booted after manually running `kpartx`, `cryptsetup` and `lvm` in (initramfs)?
