I do not really know how to check that, I do not see anything about it
in my bios...

mythfrontend log during the jumps (from the time the audio disc is
inserted, does not look good...):

I do not see anything specific in dmesg..
Than again it is a lot of output...  (is there anything specific to
look out for?)

Thanks,
