Kernel Panic on PowerMac G4 "Digital Audio" during boot

[Alexander Coers]

Hi John,

I have no clue. I just tried Release 10.4 and this works without issues (loading the kernel from OF takes ages compared to CD-ROM boot) except that I need to disable DMA for internal IDE. I guess there is an incompatibility with the SATA/PATA adapter I use.
Should I create a bug report?

Bye,
 Alexander
