Hi all, I think one _must_ disable the decoders first by disabling space in PCI_COMMAND register. Check u-boot how it does: http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=drivers/pci/pci_auto.c;hb=HEAD It first disable the cmdstat = (cmdstat & ~(PCI_COMMAND_IO | PCI_COMMAND_MEMORY)) | PCI_COMMAND_MASTER; And then goes to decode. VIA bridge has also _default_ enable decode, so it blows up very badly when probing without decode enabled.
