Andreas, first of all I thank you for the advices and your time. 1st trial: Lucid live CD. After getting back from suspend mode the whole X locked up. So I changed to console which behaved very weird(It didn't accept commands at all). Hence I couldn't get useable information from logs. 2nd trial: I installed linux-image-2.6.33-020633rc8-generic_2.6.33-020633rc8_i386 kernel and tried the same steps with the result of huge cpu load. Ksoftirqd used up 100% of CPU time. Logs attached to the post.
