Package: linux-image-2.6.39-1-amd64
Severity: important
Tags: sid

The cdrom_id program from the udev package (version 167-3) "refuse to freeze"
with a linux 2.6.39. That prevent the system to suspend.
It works will with a 2.6.38 kernel, then the problem starts with the 2.6.39
kernel.

The 170-1 version works well with the 2.6.39 kernel.

Here are the linux messages:
