Hi Borislav, > Make init_amd_nbs() arch_initcall_sync() so that it executes after PCI init. I described earlier in this thread why such option is not working - let me quote myself: It's not enough for running init_amd_nbs() to have only pci_arch_init() done. We need the pci bus to be created and registered with all devices found on the bus. We are traversing through them and trying to find northbridge VID/DID. Due to the above, we need to run init_amd_nbs() only after acpi_scan_init() that is invoked from acpi_init() which is registered as subsys_initcall. That's why the trick with switching init_amd_nbs() to arch_initcall_sync will not work. We have a kind of chicken-and-egg problem here. Or is there something I missed? I wonder if there is upstreamable option to control order of the drivers' init by forcing link order? Best Regards, Jan
