Hi
While testing kernel 2.6.34-rc5-git10 on an Acer Aspire One 110L netbook
(Atom N270, i945GSE chipset, hyperthreading enabled and not configurable,
BIOS 3309), I reproducably encounter the following oops while shutting down
(manual transcription below):

I don't encounter this problem on 2.6.26-2.6.33(-stable), which didn't
have Moorestown/ ABP_Timer support of course, and disabling X86_MRST (and
subsequently APB_TIMER) avoids the problem as well; it does not happen
while rebooting, but only during a full system halt. With X86_MRST &&
APB_TIMER disabled, everything seems to work fine.
Tested on an up to date Debian unstable system:
ii gcc-4.4 4.4.3-9 The GNU C compiler
ii binutils 2.20.1-7 The GNU assembler, linker and binary utilities
While I can test any potential patches, debugging is a little limited
without serial access to the netbook and because a netconsole doesn't work
at that shutdown stage anymore.

I can confirm that this patch applied on top of 2.6.34-rc5-git10 fixes
my shutdown problem; no further oops has shown within 20+ shutdowns so far,
while it was 100% reproducably before. Sorry that I didn't notice
https://bugzilla.kernel.org/show_bug.cgi?id=15786 before.

I work for Intel. I don't speak on their behalf.
