Bug#752187: cdrom: Installer hangs on UEFI hardware when creating EFI-fat16 partition

[Peter Jones <pjones@pmade.com>]

Package: cdrom
Severity: important

Dear Maintainer,

   * What led up to the situation?

     Install Jessie on UEFI laptop.  Not sure if it's relevant but I
     also configured a guided install with full-disk encryption.

     Switching to virtual console 4 shows that after about 2 minutes a
     MCE hardware error is triggered.  Other virtual consoles continue
     to work, but installer is hung.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

     Workaround by first installing Wheezy (at least get it to format
     the drive).  Then Jessie installer works after Wheezy installer
     creates the partitions.

   * What was the outcome of this action?

     Jessie installer works after using Wheezy installer.

   * What outcome did you expect instead?

     Jessie installer should not hang while creating EFI-fat16
     partition.
