Do you need more information? Please ask and I'll try to provide it!
Comment 1 Rafael J. Wysocki 2012-01-23 21:13:19 UTC
This appears to be a memory corruption, but it's hard to tell where it happened, because there's not debug information in your kernel (i.e. I need to know function names instead of the addresses in the call trace).
Comment 2 Klaus Mueller 2012-01-23 22:18:03 UTC
This means, I have to install the debug-kernel? ksymoops was unable to resolve any address. Why is the kernel suddenly tainted???

I got another oops - a few minutes later, the machine was dead:

Is this a distro kernel?  If so, what distro and what kernel?
Comment 4 Klaus Mueller 2012-01-23 22:55:38 UTC

Unfortunately, ksymoops doesn't work:

ksymoops 2.4.11 on x86_64 3.2.1-3-debug.  Options used
     -V (default)
     -k /proc/kallsyms (default)
     -l /proc/modules (default)
     -o /lib/modules/3.2.1-3-debug/ (default)
     -m /boot/System.map-3.2.1-3-debug (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Warning (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a valid ksyms file?
No modules in ksyms, skipping objects
