Hi all I have previously posted regarding a message about a transparent bridge message I get when booting my laptop.
PCI quirk: region 1000-107f claimed by ICH6 ACPI/GPIO/TCO PCI quirk: region 1180-11bf claimed by ICH6 GPIO PCI: Ignoring BAR0-3 of IDE controller 0000:00:1f.1 PCI: Transparent bridge - 0000:00:1e.0 PCI: Bus #07 (-#0a) is hidden behind transparent bridge #06 (-#07) (try 'pci=assign-busses') Please report the result to linux-kernel to fix this permanently There doesn't appear to be any ill-effects from this, but a permanent fix is probably a good thing and so I'm reporting it. I have however tried "pci=assign-busses" as suggested. While this does make the above complaint go away, it introduces two other things, one a lot more serious. The first thing I've noticed is that when "pci=assign-busses" has been specified, I get the following in the dmesg: Clocksource tsc unstable (delta = -434140355 ns) I don't seem to get this if assignbusses hasn't been given. The second effect of "pci=assign-busses" is that it prevents Linux powering the laptop off; pressing the power button triggers an ACPI event as it should and Linux proceeds to close everything down. However, when it comes time to actually kill the power the screen goes blank and the backlight gets turned off, but power remains on until I force it off by holding the power button down for 4 seconds. I have verified this with 2.6.18, 2.6.19 and 2.6.20. Furthermore, the RT patchset does not change the behaviour. Something mighty odd seems to be going on here. Does anyone have any ideas or suggestions of things to try?
