Title:
  Lost IRQ drop harddisk

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: linux-image-2.6.32-21-server

  The hardware is working fine for 2 years. Cause some ext4 problems I
  decide to upgrade.

  After the Upgrade to 10.04LTS my server lost a random harddisk once a day.
  (Ubuntu 2.6.32-21.32-server 2.6.32.11+drm33.2)
  This occure with one disk of the sata soft-raid or sometimes with the ide root partition.

  After a reboot all is working fine for a couple of hours.
  A sync of 6 TB soft-raid (6*1,5GB sata) is often complete successful in this time.

  PS: I note in the Call-Trace a recursion in sync_buffer. Is this really right ?
