Well, I can confirm that the panic is definately NOT ACPI related. It happens in my debug kernel regardless of whether or not I have the acpi.ko module loaded and/or hint.acpi.0.disabled=1 set. I don't have atapicam in the kernel in question either. I'm going to try that patch from Maxim today. I'll report my findings. -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O. Box 2605 // Cleveland, TN 37320-2605 423-559-LINK (v) 423-559-5145 (f) http://www.wingnet.net
