Title:
  dmraid hangs trying to start ICH9R RAID 5

Bug description:
  When dmraid tries to activate a raid5 array, it appears to send down
  bad parameters to device-mapper, causing it to print:

  device-mapper: table: 252:9: raid45: Invalid RAID device offset parameter
  device-mapper: ioctl: error adding target to table

  After that it appears that it tries to destroy the new unconfigured
  device, but this hangs in the uninterruptable state in
  dm.c/__dm_destroy(), apparently waiting for a leaked reference that is
  never released.  I can not find the source of the leak.
