The last initcall_debug messages are:

    calling atiixp_ide_init+0x0/0x20
    initcall atiixp_ide_init+0x0/0x20 returned 0 after 0 msecs
    calling piix_ide_init+0x0/0xc0
    initcall piix_ide_init+0x0/0xc0 returned 0 after 0 msecs
    calling ide_scan_pcibus+0x0/0x100

ide_scan_pcibus doesn't return. I tried shoving some printks in there,
but as soon as I did it instead locked up in pci_init. Is it worth
continuing this approach or will doing so not give useful results
anyway?
