Bug description:

  thanks to the help of Ben Hutchings we've found an issue with several
  low end Dell servers which is beeing tracked in Debian bug

  Since we see the same issue on Dell R210 II with Ubuntu 10.04 (which
  is aswell Linux 2.6.32 based) and
  http://www.ubuntu.com/certification/hardware/201107-8313/ claims
  that's supported hardware, it would be great if you could take a look
  at the proposed fix aswell.

  You can reproduce the issue easily when issuing a 'racadm racreset' via SSH on the included iDRAC 6 KVM card. You'll afterwards
  see one of the [events/$x] processes of the kernel in state D and interaktive logins on the operating system will no longer
  work. You can still connect with 'ssh -T'.
