No, I do not get any serial outout after the OS is loaded!

I have a PCI SI3112 card with one HDD drive and a CDROM drive attached and a PCIE sound card with VIA TREMOR VT1723 chipset.

As the Computer gets quite warm, I already suspected temperature problems and utilized an additional fan, no difference.
I also suspected my 300W PSU, but I measured the consumption and the system takes only about 70W, so that can't be the problem as well.

Maybe some testing tools will narrow down the source of the problem? I will have a look on MorphOS storage if I can find some stress test tools...
Another thing I can test is to change my SATA controller card. Maybe another chipset will perform better?
