Software Environment:
Problem Description:

on boot, system hangs very early, last line is:
ACPI: Assume root bridge [\_SB_.PCI0] bus is 0

tried some acpi boot params but went nowhere.
tried some dgb_level, but seems impossible to catch msgs as it seems the 
problem is a loop, hence same msgs get printed too fast to anything but that
they look like a repeated pattern. CPU gets hot, if left in this state.
With acpi=off system hangs early on boot as well, at 'probing PCI ...'

Steps to reproduce:
Comment 1 Len Brown 2006-04-19 18:34:24 UTC
There have been zero ACPI changes between 2.6.16.1 and 2.6.17-rc1
bumping this over to the PCI sub-system.
Comment 2 Daniel 2006-06-20 05:01:38 UTC
I experience the same on 2.6.17 final on a HP Compaq dc7600.
Linux 2.6.16.1 works fine.

When booting with acpi=off, console shows the following before freezing:

unknown bus type 255. (repeatedly)
..TIMER: vector=0x31 acpi1=-1 pin1=-1 acpi2=-1 pin2=-1
...trying to setup timer (IRQ0) through the 8259A... failed
...trying to setup timer as Virtual Wire IRQ... works.
HP Compaq series board detected, selecting BIOS-method for reboots.

then it is frozen.

Comment 3 Greg Kroah-Hartman 2006-06-27 16:45:08 UTC
Based on email comments, this is fixed in 2.6.17-git10, so am closing it.
Comment 4 Thomas Pinz 2006-08-12 12:38:23 UTC
On my Toshiba Portegee M400 the problem still exists. 
I tested 2.6.17.4, 2.6.17.6, 2.6.17.8, 2.6.18-rc2, 2.6.18-rc3-git7, 2.6.18-rc4
