Hi,

when booting my hp compaq nc 8000, the 2.6.19.2 kernel log asks me to
report something to linux-kernel which I am doing now:

Jan 13 12:44:13 scyw00225 kernel: PCI: Probing PCI hardware (bus 00)
Jan 13 12:44:13 scyw00225 kernel: ACPI: Assume root bridge [\_SB_.C044] bus is 0

When I try pci=assign-busses on the kernel command line, the four
lines vanish:

Jan 13 12:29:29 scyw00225 kernel: PCI: Probing PCI hardware (bus 00)
Jan 13 12:29:29 scyw00225 kernel: ACPI: Assume root bridge [\_SB_.C044] bus is 0

Jan 13 12:29:29 scyw00225 kernel: ACPI: Power Resource [C0E6] (on)

I do not have a single clue what that mean; the notebook runs fine
just with or without pci=assign-busses. 

Is there something I shold do? Is there something you should do with
the kernel?

Greetings
Marc
