Found multiple issues related to the ide-pmac <-> mediabay & ide core interaction changes. I've done some fixes but it's not quite there yet. It looks like it's getting IRQ issues with the mediabay CD, for some reasons looks like something unmasks the interrupt before there's a handler or around those lines... I get an irq "nobody cared" error, it gets disabled, and then hdc gets lost interrupts. I'll dig a bit more and if I can't find what's up tonight, will send you my current patches in case you have some other idea. Cheers, Ben.
