Lockup with ASMedia Sata

Greetings All,

I have an ASUS Sabertooth 990FX R2.0 motherboard with Suse 13.1 installed. If I do NOT use the ASMedia Sata hardware (White plugs) everything
works OK. If attempt to utilize one of these plugs, the system experiences lockups on any sort of interrupt; for example, putting a DVD in a DVD-ROM drive.
There are NO error messages generated on these lockups, and the only way to recover is a hard-reset/power off.

I suspect this to be a Hardware issue. However, before I incur the pain of an ASUS RMA, does anyone know if there is a known driver issue with this MB or the chipset supporting these devices? I HAVE updated the BIOS to the latest and greatest, without any change in this problem.

Thanx in advance
