Bill Paul ba3af76df7 Modify the pci_cfgdisable() routine to bring it more in line with ... other OSes (Solaris, Linux, VxWorks). It's not necessary to write a 0 to the config address register when using config mechanism 1 to turn off config access. In fact, it can be downright troublesome, since it seems to confuse the PCI-PCI bridge in the AMD8111 chipset and cause it to sporadically botch reads from some devices. This is the cause of the missing USP ports problem I was experiencing with my Sun Opteron system. Also correct the case for mechanism 2: it's only necessary to write a 0 to the ENABLE port.		2005-10-25 04:53:29 +00:00
