Before this commit I could boot with "pci=noacpi acpi_sleep=s3_bios resume=/dev/hda2" without an oops. Unfortunately git revert d6ece5491ae71ded1237f59def88bcd1b19b6f60 does not work without merge conflict on top-of-kernel.

It's actually a "MSI S260". You may find more information for this notebook on the tuxmobil page. http://tuxmobil.org/msi.html -- Gerhard
