I recieved this oops after rearranging my SMP system to include a large (>100GB) raid5 array and copying approximately 15GB to it. The array was still synchronizing at the time. Motherboard is MSI 694D. RAID array in question is attached to the Promise 20265 chipset. No drives were attached to the VIA IDE controller. Anyone knowledgable have any ideas? I have not seen this since.
