pci hidden behind transparent bridge

[Ni@m]

Hi! I noticed such message:

"PCI: Bus #07 (-#0a) is hidden behind transparent bridge #06 (-#06)
(try 'pci=assign-busses')
Please report the result to linux-kernel to fix this permanently"

on my
Linux niam 2.6.22-rc6-cfs-v18 #6 Mon Jul 2 20:19:25 EEST 2007 i686
Intel(R) Celeron(R) M processor 1.50GHz GenuineIntel GNU/Linux

What does it mean??

Is this a regressions?

Have you tried to boot kernel with "pci=assign-busses" param?

There's about 8 gazillion of these reports that have been in bugzilla
since the dinosaurs roamed the lands.   Just ripping the printk out
would be my preference.

There is a patch in -mm and in my queue for 2.6.23 to revise the message
to send the information to the correct person responsible for it.

It seems like whoever added the message saying to report this to LKML 
hasn't responded to these reports. Any patches adding such messages in 
the future should really include details of what they expect to be done 
with the reports..
