Here is the output of my instrumentation: Linux agpgart interface v0.101 (c) Dave Jones agpgart: DEBUG 0 agpgart: DEBUG 1 __pci_register_driver: In function __pci_register_driver: driver = agpgart-amdk7, multithread = 0 __pci_register_driver: Before Spinlock __pci_register_driver: Before List Init __pci_register_driver: Before Driver Register __pci_register_driver: Error = 0 __pci_register_driver: Returning 0 The DEBUG 0 and 1 are coming from agp_amdk7_init() There is a DEBUG 2 at the top of agp_amdk7_probe(), even before pci_find_capability, but the function never gets called. I assume an error of 0 means no conflict. Any further steps to take for this? I would really like my AGP working :S Especially since lspci obviously detects it, even tells me it supports 1x, 2x and 4x. PreZ :S
