Title:
  ata lost interrupts, blocked waiting for disk

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  At some point on 29th July my Ubuntu 10.04 machine became
  unresponsive. I recognise this was a while ago, but wanted to register
  it at least in case other people had the same issue or it came up
  again. I did capture the full syslogs from the time, but unforunately
  the bug reporting tool will have atached my 11.10 details.

  When I tried to use the machine at least networking and crond were
  still running, but display was not outputting anything and I couldn't
  log in using VNC or SSH. Machine was pingable and showed open ports.
  After rebooting, I saw these errors in the logs:

  sam@wildthing:/var/log$ zgrep "lost interrupt" syslog* 
  syslog.1:Jul 29 08:12:13 wildthing kernel: [176483.080064] ata7: lost interrupt (Status 0x58)
  syslog.1:Jul 29 08:36:24 wildthing kernel: [177934.080065] ata7: lost interrupt (Status 0x58)
  syslog.1:Jul 29 12:59:19 wildthing kernel: [193709.120067] ata7: lost interrupt (Status 0x58)

  syslog.1:Jul 29 15:16:05 wildthing kernel: [201915.120092] ata7: lost interrupt (Status 0x58)

  They are followed by related messages, then finally some tasks look
  like they are blocking writing to disk:

  sam@wildthing:/var/log$ grep blocked syslog.1

  Previous boot was on 27th:

  sam@wildthing:/var/log$ zgrep "kmsg started" syslog*

  ata# assignment has swapped around this boot, so nothing on ata7 but I
  would guess that is normal.

  I understand this could be a hardware problem, but I don't know what
  to do to track this down further, so assigning to the kernel for now.
  Please request further information if required.
