[Bug 43732] maybe nothing to do with acpi at all, sorry

[Thomas Koechli]

As I learned from a friend just now, the output from kern.log I postet has nothing to do with the freeze but much more with the booting process afterwards. Im very sorry for pointing in the wrong direction.
Nevertheless the annoying bug keeps on crashing my new ubuntu dapper and I have absolutely no idea why.
Again, I'm sorry. I just tried to help. But - speaking as a beginner on Linux and Ubuntu - it's not that easy.

System freezes randomly from Dapper live install and dist-upgrade unless booted with "acpi=off"
