-static struct pci_device_id __initdata pci_eisa_pci_tbl[] = { +static struct pci_device_id pci_eisa_pci_tbl[] = {
did not help.
Printing dmesg in verbose showed below three lines.
[ 0.262828] EISA bus registered [ 6.291117] EISA: Probing bus 0 at eisa.0 [ 6.295445] EISA: Cannot allocate resource for mainboard
Manual printk() tracing showed below callchain.
virtual_eisa_root_init() calls eisa_root_register(). eisa_root_register() calls eisa_probe(). eisa_probe() returns -EBUSY since root->force_probe == 0. eisa_root_register() calls release_resource() and returns -EBUSY. virtual_eisa_root_init() calls platform_device_unregister() and returns -1.
Also, eisa_root_register() in pci_eisa_init() is not called.
So, it seems that something is wrong with cleanup. pci_unregister_driver() is missing?
