Hi Chris,

the log starts here - before May 30 21:40:52 there is for 6 hours
nothing. It's the beginning of the logging. I'm sorry to say so, but I'm
absolutely unable to boot into 3.0rc1
I used a complete with luks encrypted btrfs partition, there is only
another /boot partition with ext4 - and this system is running since
march 2010. On other kernels (2.6.38 or 2.6.39) - the logging starts
much more early - but like I said - the load was unbelieveable high the
whole time, the hard disks reached maximum temperature (so it was very
hard to lay the hands on the computer) - and my only explanation are
these entries.
