will: down_read(&pci_bus_sem);
also enable interrupts?
Since that is called:
init/main.c start_kernel
kernel/params.c parse_args("Booting kernel"
kernel/params.c parse_one
drivers/ide/ide.c ide_setup
drivers/ide/ide.c init_ide_data
drivers/ide/ide.c init_hwif_default
include/asm-i386/ide.h ide_default_io_base(index)
drivers/pci/search.c pci_find_device
drivers/pci/search.c pci_find_subsys
down_read(&pci_bus_sem);

begin { telegraaf.com
