Someone replied to this email and suggested that i run
ksymoops. I have accidentally delete his email..so i
dont remember who it was, but basically, I am looking
into whether he or someone else is good at
translating the output.
I thought the lines marked by = were of
interest to ksymoops, but am not able to translate
them.

Usually system hangs for a while, then after some
minutes, goes back into operation mode. During hang,
ofcourse, no ps or top or w, anything, so I cant
really narrow down the problem.
And also below is the kernel warning messages::
