Hi Rob,
I can no longer boot my old Mac Mini G4 using a custom config. After a
tedious bisect it appears that (*). Since Mac Mini does not provide
any serial port I cannot provide a kernel message dump (wish there was
some kind of null modem serial cable). All I can see is some crazy
stuff going on with ATA DMA/66 & DMA/100.
Is there anything suspicious in this commit which may prevent this
machine to boot ?
Yes, it's broken. You need this patch[1]. Sorry for the breakage.
Rob
