Paul,
I'd previously reported a problem where the PCI subsystem was getting inited before the memory subsystem. In the unusual case of an EEH failure, this resulted in a crash in kmalloc, which I hacked around with a if(!mem_init_done).
You mentioned that the sequence of inits seemed wrong, that the PCI init should be done later, after the memory init. I think I agree; but when I took a very very quick look at the code, there was no obvious hook in later init to move the PCI init over to.
Are you pursuing this further? Should I dig into it? Any bright ideas? Am I missing something obvious?
There are several spots in in the powerpc PCI init code where a boot_mem alloc is used instead of kmalloc, and this boot_mem is then hacked around in the case of a PCI hotplug remove. It would be nice to fix this...
