While I ran the powerpc64 installer again with the drive already initialized with a file system it didn't panic. So I ran newfs from the shell and had it panic the kernel. This is a PowerMac G5 (PowerMac9,1), running the powerpc64 installer from CD. The panic happens for both Apple Partition Tables and DOS MBR tables. Please let me know if there's anything I've missed or things that I can test to help? -- You are receiving this mail because: You are the assignee for the bug.
