It's odd that the ahci driver returned -EBUSY. Maybe this is due to "we
have legacy mode, but all ports are unavailable" in ata_pci_init_one().

ata_device_add() has given up, has called ata_host_remove() and then we
presumably oopsed over incompletely initialised class stuff. It's likely
that this oops is a second bug - a consequence of the -EBUSY.

Could be acpi, yes.
Parenthetically, I wouldn't have thought that this error should be fatal
for the driver.

Don't know, sorry. But this kernel had oopsed, hadn't it?
