  jammy beta (220330) live server arm64 iso failed to boot Hisilicon D06
  with virtual CD

Status in linux package in Ubuntu:
  Incomplete
Status in subiquity package in Ubuntu:
  New

Bug description:
  = Description =
  Platforms: Hisilicon D06 (d06-1 and d06-3 in our lab)
  Image: Jammy Beta (220330)

  = Steps to Reproduce =
  1. Boot the system with the iso from d06's virtual CD of BMC
  2. Launch the kernel via the default grub entry

  = Expected Results =
  The kernel and image are loaded via the virtual CD, and then subiquity is launched.

  = Actual Results =
  After the grub stage, when loading the kernel we see (check d06-3.log for the full log details):
