Hi,

The x86 git tree, as of HEAD commit

commit a9efd1225e6e0e78ceeaecc04cec1d428eb8173f
Author: Mike Travis <travis@sgi.com>
Date:   Fri Apr 4 18:30:16 2008 -0700

    x86: modify Kconfig to allow up to 4096 cpus

doesn't want to work on one of my testboxes (x86-64 desktop,
AMD-based).

First, the X server doesn't want to start (it says it couldn't mmap the
framebuffer).

Second, if I try to suspend the box to RAM, it enters a state it cannot
leave until power is physically cut from it (using the power button to power
off / power on the box doesn't help).

At the same time, 2.6.25-rc8-mm1 works just fine on this box.

Any ideas what to revert?

Thanks,
Rafael
