Again the Fedora release looms and I set about installing rawhide on every PowerPC machine I can find. And again I can't find much wrong with it that's specific to PowerPC.

We thought we'd found one when the kernel wouldn't boot on 32-bit Macs, but that turned out to be a generic memory allocation bug which just happened to be triggered with our configuration by the PowerMac IDE driver. If it hadn't been relatively easy to reproduce in the ppc32 testing, it might have taken much longer to find it.

It's not the first time that the existence of Fedora on PowerPC has had a beneficial effect across all architectures.
