Title:
  ata1: device not ready (errno=-16), forcing hardreset

Status in “linux” package in Ubuntu:
  Incomplete
Status in Debian GNU/Linux:
  New

Bug description:
  The following message appears some time after booting ubuntu, 
  but the extrange thing is that the machine has two hard disks in raid0 (mirror) 
  and it only happens in the first one.

  Some times raid rebuild crashes and I have to tell the system that some partitions
  belong to the raid (it removes the references). 
  Raid partitions 1 and 3 are the problematic ones, 
  while raid partition 2 always survives to the hard reset.
