1GHz pbook 15", linux 2.6.14-rc2 oops on resume

[Soeren Sonnenburg <kernel@nn7.de>]

Hi all,

when a dvd featuring some iso content is in the dvd-drive and the
machine is put to sleep mode, it will give the following oops on resume.
It is working without problems if no media is in the drive.
Voluntary preemption is ON.
Find below the dmesg output when a dvd is in the drive.
