The following patch is causing problem with the vxge driver/adapter on
HP x86-64 systems. Reads to bar0 to return 0xffffffffffffffff instead
of their intended value.  This prevents the vxge module from loading
by failing sanity checks in the driver for certain values in bar0.  We
are not seeing any issues with this patch on non-HP systems in our
lab.

Can this patch be removed from 2.6.37 until a better solution can be
found?

Thanks,
Jon

    x86: allocate space within a region top-down
    
    Request that allocate_resource() use available space from high addresses
    first, rather than the default of using low addresses first.
    
    The most common place this makes a difference is when we move or assign
    new PCI device resources.  Low addresses are generally scarce, so it's
    better to use high addresses when possible.  This follows Windows practice
    for PCI allocation.

Can you try my for-linus branch and see if the problem still exists
there?  It's at
git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6.git.

There were several issues related to that patch, and it's about to
be reverted.  I am curious about the failure you're seeing, though,
and I'd like to understand the cause and make sure it's one of the
issues I've already investigated.

Can you send me the complete dmesg log of a failing boot?

Thanks,
  Bjorn

Below is the dmesg of a failing system.

Thanks.  This is interesting.  All the reported PCI windows are below 4GB:

But the BIOS configured many devices *above* 4GB (and they probably
work fine there), so we complain about them, zero out their resources,
then think they conflict with some PNP devices (which they really
don't):

ACPI helpfully tells us that the high 6MB below 4GB is reserved, but
we don't handle that correctly:

> pnp 00:08: [mem 0xffa00000-0xfffffffe]
> system 00:08: [mem 0xffa00000-0xfffffffe] could not be reserved

And finally, we drop some of those PCI devices, including the vxge
device on top of that ACPI PNP0C02 device, which of course doesn't
work:

So there's probably a BIOS bug (not reporting the windows above 4GB),
and definitely a Linux bus (allowing PCI to allocate things on top
of ACPI devices).

This is a known Linux issue, and the top-down allocation scheme made
it much more likely that we'd run into problems like this.  Reverting
to bottom-up allocation doesn't fix the problem, but makes it much less
likely that we'll trip over it.

Thanks a lot for reporting this and collecting the dmesg!

Thanks for taking a look at it.  Let me know if there is anything I
can do to help resolve this issue.

Thanks,

The for-linus branch does NOT have the issue
The master branch does have the issue
