Subject: [regression] 2.6.37-rc1: Freeze while booting on HP nx6325

Hi, I have a problem with 2.6.37-rc1. My HP nx6325 freezes during boot.
It happens after printing lines:

[    0.298457] atiixp 0000:00:14.1: not 100% native mode: will probe
irqs later
[    0.298515]     ide0: BM-DMA at 0x7040-0x7047
[    0.298573] atiixp 0000:00:14.1: simplex device: DMA disabled
[    0.298625] ide1: DMA disabled
<Freeze>

This didn't happen in 2.6.36. I bisected between 2.6.36 and 2.6.37-rc1:

    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.

Reverting above patch from latest linus-tree resolves problem.
