[Bug 1065281] Re: Installer crashed when trying to partition 4k/4k sector hard disks

[Steve Langasek]

Reading through the bug log, it appears that the fixes currently staged
in precise-proposed are all necessary, but not sufficient, for getting
the system to install and boot with 4k disks.  Since the validation
being done to date for 12.04.3 is with images that include these
packages, and since 12.04.3 is meant to happen imminently, I believe the
right thing to do here is to go ahead with publishing what we have to
date.

Bug description:
  partman_server crashes on Ubuntu 12.10 server for amd64 when trying to
  partition an Advanced Format (4k / 4k sector) hard disk.

  Disks that utilize 4k sectors with 512 emulation work fine.  The
  installer has no problems with those.

  Steps to Reproduce:
  1) Begin the installation in EFI mode. 
  2) At the disk partitioning stage, select "Guided use Entire Disk" or "Manual"
  3) Review and accept the proposed partitioning scheme and write changes to disk. 

  Actual Results:
  The system will attempt to create a the EFIboot partition.  At this stage the installer appears to hang.   Pressing Ctrl+AltF4 reveals that parted_server has crashed with the following message:

  parted_server[13865]: segfault at 22fa000 ip 00007fa6eb74bee7 sp
  00007fffec3ab500 error 4 in libparted.so.0.0.1[7fa6eb735000+64000]

  Expected results:
  Installation should carry on without a crash.
