[Bug 36180] Hibernate doesn't work properly

[Christian Meyer]

Public bug reported:

Affects: linux-meta linux-image-686 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Sometimes my laptop (IBM Thinkpad T41) doesn't properly shutdown on hibernate. It seems that the machine reads/writes something from harddisk and doesn't stop doing that.
This problem doesn't always happen, which is a little bit strange.
The latest dapper is installed on my machine.

Kernel is: 2.6.15-19-686 (2.6.15-19.29)
