Package: linux-image-2.6.26-1-686
Version: 2.6.26-13
Severity: important

Hi,

I experienced random freezes at shutdown with 2.6.26-1-686 on my
ThinkPad T42p.

I'm sorry, but I can't provide much diagnosis. There are no log file
entries and it seems the problem occurs in a late shutdown phase. However,
the root filesystem is still mounted. I noticed that if and only if I get the
message
  "Shutting down: hda"
the shutdown works fine and the computer is turned off. There is a 50%
change that the shutdown works.

Maybe the following is important: I'm using ...

 * the VirtualBox 2.1.0 Kernel modules
 * the madwifi WLAN driver
 * the open source ati/radeon Xorg-driver

The problem disappeared after a transition to 2.6.28 (home brew).

Cheers,
  Michael

Marking as fixed in 2.6.28 in unstable.
 
It will be difficult to pinpoint a fix for Lenny, it's likely some sort
of ACPI problem. Does the system power down reliably without the vbox
module and the madwifi driver?

Cheers,
