Laptop freezes

[Nils]

Hi all,

I'm running Kubuntu Dapper on my compaq nx7010. Dapper ran fine for
some time, but today and yesterday the laptop frooze 2 times, i
checked /var/log/messages but didn't find anything about that.

I don't have any proprietary driver installed (like fglrx), but I use
hibernate, which has been unstable some time ago (but worked fine for
me so far..).

Now I'm looking for ideas to figure out what caused my laptop to freeze..
