Bug 8748

Most recent kernel where this bug did not occur: -
Distribution: Debian Lenny/Sid x86-64
Hardware Environment: Toshiba Tecra A9 (Core2Duo on i965GM)
Software Environment: 
Problem Description: My kernel complains about a bus hidden behind a bridge on my Intel ICH8 / i965GM based laptop:

PCI: Bus #06 (-#09) is hidden behind transparent bridge #05 (-#06) (try 'pci=assign-busses')
Please report the result to linux-kernel to fix this permanently

I guess I reported it now, so you can hopefully fix this, whatever the problem exactly is.
BTW: I did not experience any serious problems, I just saw the line in dmesg and decided that it's a nice day to do what it says and file a bug report :P

Here some more output from dmesg, maybe it's useful:
