Title:
  Ubuntu 20.04 boot hangs when laptop unplugged

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On Dell Latitude 5500 laptop, dual-boot Ubuntu/Windows, Ubuntu 20.04
  64-bit, 5.4.0-33-generic, Ubuntu boot stops with blank screen when the
  laptop is unplugged, even in recovery mode.

  After plugging in power after a failed boot, the following message is shown 
before the splash screen:
  [ 0.468311] Initramfs unpacking failed: Decoding failed
  /dev/nvme-n1p6: clean, 470502/4800512 files, 6138995/19200000 blocks

  As long as the laptop is plugged in before selecting Ubuntu in GRUB,
  it will boot, but it never finishes booting if it is unplugged, even
  in recovery mode. It also occurred in Ubuntu 19.10.

  When the boot freezes even in recovery mode, the bug should be
  reported against the kernel according to this page:
