It's basically calling pci_find_slot in an interrupt context, which ends up calling pci_find_subsys which complains about it. One possible solution would be for the code to be changed to call pci_find_slot during module initialization and save the return value, and use that instead. Yes, I know this prevents hotplugging. Who hotplugs graphics cards? ;) --==_Exmh_668682134P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFADtEDcC3lWbTT17ARAkolAKC0Bsttm2gn8U8maWRfuHx2Ji+uCwCeI/Pw 4uUuV6n8lRoncT+qbO7W0Bw= =j/My -----END PGP SIGNATURE----- --==_Exmh_668682134P-- -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
