Subject: "ignoring host bridge windows from ACPI" in a recent laptop

Hi!

I have a Sony Vaio VPCF11M1E since early this year. Looking through the
output of `dmesg`, I noticed
----  snip  ----
pci_root PNP0A08:00: ignoring host bridge windows from ACPI; boot with "pci=use_crs" to use them
----  snip  ----
So I tried that.
The laptop boots and works without problems so far. I attached a diff of
the first approx. 630 lines of the `dmesg` outputs without and with the
above parameter. It gets pretty messy afterwards because (at least) the
USB and/or SATA initialization runs apparently in parallel.

After finding http://lkml.org/lkml/2010/2/12/174, it seems that we might
need another quirk to activate that automatically.

At the end, I lost also dozens of
----  snip  ----
name_count maxed, losing inode data: dev=00:07, inode=
----  snip  ----
lines (which are also not in the attached diff). I don't know if that
has something to do with the above.

I can provide the full diff and/or the two dmesg outputs (and pretty
much anything else - just tell me what you need).

	Bernd
