Title:
  Installation fails on machine with Intel VROC

Status in subiquity package in Ubuntu:
  New

Bug description:
  I'm trying to install Ubuntu 22.04 on a server which has two M.2 disks
  in RAID 1 using Intel VROC.  If I accept the prompt to update
  installer to 22.07.1, then it fails while probing for destination
  blocks devices.  If I proceed without updating, it works fine.

  The server is a Supermicro 740GP-TNRT.

  I'm attaching the full output from `/var/log/installer` and I believe
  the relevant portion is this:

  ```
