Greetings,
Currently I have FBSD 6.1 release (custom build, DMI, DRM, took out some
drivers that I don't use) however, 6.1 release generic didn't quite work
either*. (Works on a different (slower) harddrive controller)
ACPI doesn't seem to work on this computer.
The problem is that I have two host -> PCI adapters, and two PCI -> PCI
bridges
in my computer, and a Symbios 53c896 behind one of them isn't being seen.
Essentally, there is... (edited output from pciconf -lv)

As you can see, pcib2 and pci2 have been dropped. I can see that within the
source code (pci_bus.c L#387) there is an if statement that looks for duplicate
busses. I inserted a quick printf statement in there, and it showed up, once.
Thus, something, somehow is being kicked. (Due to my lack of knowledge with
regards to C code, I don't know how to find out what board is, because I
don't
know how to find out how the variable has been defined in C. (%x, %d ...)

==================================================================================
if you look at 00:11.0 & 00:11.1, the last lines have "Region 0: Memory
at
<unassigned> (32-bit, prefetchable)" and "Interrupt: pin ?
routed to IRQ 255",
respectively.

==================================================================================
So, 0:11.0 has a base address, it's 0x8
As for 00:11.1, perhaps the code is attempting to assign an irq to the pci-pci
bridge (thinking that it's a host), thus, can't find it, assigns a irq
of 255
and something along the lines kicks out irq=255.
Any suggestions for hacks??
Thank you for your time.. More info will be provided upon request.
