Luckily I could catch some information before the last crash. With the newer kernel (2.6.28-12-generic) the freeze does not appear the old way, but still there is something massively wrong. Currently the system freezes mostly on shutdown or on suspend.
Right now there was the following situation: PC running for 2h (fresh booted), Thunderbird, Firefox turned on, some Music streaming via mplayer plugin. Suddenly Firefox ends responding; at the same time, the System Monitor Tray Icons stopped working, which is a good indicator for that situation. I just grabbed the syslog entries, shutdown was again not possible, all programs are closed, since then all interaction is dead.
