I posted a couple of months ago regarding enabling libata.atapi on a Digital Alpha 164LX, equipped with a Silicon Image 3114 controller. I decied to give kernel 2.6.16 (release, was previously using rc-1) a shot, and it no longer longer panics. I still have a Lite-ON DVD ROM drive connected via a sil3611 bridge to port number 4, hoping that I can avoid using the onboard CMD646. No panic this time, though it appears to throw a machine check. The system continues all the way to multi-user, and the Maxtor drives are usable. Hope the attached dmesg helps. Let me know if I can be of any assitance.
