[Bug 1860559] Re: [18.04.4] System fails to reboot after installation

[Łukasz Zemczak]

If this is indeed the same issue we saw in LP: #1840122, I think the
only sane way to fix this is to proceed in the same way as we did in
eoan - adding a finalrd dependency to casper. This would need pulling in
finalrd into main, but I guess that was the plan already. Hopefully the
MIR review should be fairy quick, as finalrd is the same across as in
disco.

Let me reach out to the MIR team about this.

Bug description:
  bionic desktop 20190122

  Since bionic 20191211 the system doesn't reboot after installation.

  After pressing enter to reboot, the system hangs. There is this
  message printed in a loop on the console:

  [sdb] tag#0 access beyond end of device

  (in this context sdb is the USB stick)

  20191211 includes a new kernel and a new gcc

  This is similar to bug 1840122 in 19.10 which started with the upgrade
  from kernel 5.0 to kernel 5.2. Although the error message displayed on
  the console was different on baremetal, it is identical in a VM.

  Installing finalrd helps to work around the issue. However in Bionic,
  finalrd is in universe.
