As I have previously reported, probing the PCI bus with direct access enabled fails on a machine we have here. The problem appears to be a particular device that causes everything to hang when probed. This occurs in pci.c/pci_scan_bus() under the comment "non-destructively determine if device can be a master:". The second pcibios_read_config_byte() never returns, for some reason.
The problem device looks like this from /proc/pci in 2.0.36:
Bus 0, device 21, function 0: RAM memory: Unknown vendor Unknown device (rev 0). Vendor id=4978. Device id=84c5. Fast devsel. IRQ 19. I/O at 0x0. Non-prefetchable 32 bit memory at 0x90100.
The vendor ID corresponds to "Axil Computer Inc.", who seems to be making SPARC hardware? I really don't know what the device is.
This problem applies to all recent kernels.
