Title:
  Ubuntu 15.10 crashes with RAID-10

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When trying to install Ubuntu 15.10 with a RAID-10 created the system
  crashes after some time during the installation. Hitting Alt+F4 gives
  the following output as seen from screenshots in attachments.

  It looks like kernel 4.2 have some issues with RAID-10 as we can
  install Ubuntu 15.04 (with kernel 3.19) without problems. If we
  upgrade to kernel 4.2 in Ubuntu 15.04 we get the same errors.

  We have no problems when installing without RAID, RAID-0 or RAID-1.
  We've also tried on different hardware and different disk types/sizes
  but we still get system crash.
