Attempting to mount /dev/md0 (the unencrypted /boot ) from within
dropbear/busybox results in a kernel hardlock. ILO dump attached.

Title:
  cciss driver crashes kernel during boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On a HP Proliant was running trusty with vivid kernel from backports
  originally. Worked fine with userspace upgrade to wily. When I
  rebooted with the wily linux-generic kernel however I got a stack
  dump:

  SW Raid1 on two CCISS based RAID0 disks, and dm_crypt. Kernel boots to
  prompt for cyrptoroot passphrase. After entering it and mounting
  entering the dm mapper init sequence the kernel crashes. I have a
  dropbear instance installed running from initramfs (for remote
  unlocking of root) and this is still runs.

  dmesg attached from server.
