Public bug reported:

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.
