The northbridge is an AMD RS690 and the southbridge an AMD SB600.
The boards supports RAID but I did never enable this feature.
I've updated the Phoenix BIOS from version 0.32 to 0.36 and now the softreset warning is still there but Ubuntu 9.04 works as promised (obviously older versions used to work without the update).
For one month I experienced this bug and today I completely solved it with a simple BIOS update.
My desktop PC is a NEC PowerMate VL370 with a picoBTX MS7351 motherboard.
