[Bug 1557989] Re: having btrfs installed as the fs is causing a crash when trying to install the intel-microcode package

[Brinstar]

Also wanted to mention that installing the intel-microcode package works
fine with ext4, so it seems to be btrfs related

** Package changed: ubuntu-release-upgrader (Ubuntu) => intel-microcode
(Ubuntu)

Title:
  having btrfs installed as the fs is causing a crash when trying to
  install the intel-microcode package

Status in intel-microcode package in Ubuntu:
  New

Bug description:
  I am able to reproduce a bug which causes a kernel panic when the
  following conditions are met:

  1. Xubuntu 16.04 beta 1 is installed
  2. btrfs is used as the filesystem
  3. The intel-microcode package is installed after the initial system setup is complete

  I have got an actual photo of the screen when the crash happens as I
  was unable to locate the correct log file where this would have shown
  up.

  I can provide any logs that may be useful
