I've been booting it from Open Firmware instead of MacOS lately (thus didn't give a chance to the MacOS driver to do it's own tweaking of the chip) and the machine has been reliably locking up on me. Solid lockups. I finally figured out that the lockups appear to be atyfb related and that booting with video=atyfb:noaccel fixes it. It seems that when it's lockup, the whole machine is down, that is it won't take interrupts to get to the xmon low level debugger nor anything, thus I suspect the PCI is locked up. Are there any ideas of where to look for the source of the problem ? Ben. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
