Looks like PAT is getting disabled on this platform. Can you send the
output of /proc/cpuinfo please.

Does this mean we failed an ioremap()? We still should not fail
a device ioremap _ever_. We should just fall back to UC and be
done with it. We may emit a warning if we consider it
troublesome, but we should never ever break working drivers
really.

No. We don't break ioremap. We try to fallback on UC_MINUS here. But,
there is something wrong happening in that path, that is resulting in
this issue. I am looking at that right now.
I have found another problem with this particular patch, on one of test
systems. So, let us keep the revert until I fix what looks like two
different problems here.
Thanks,

The machine has a stepping of the Celeron M chip in it with PAT errata.
I think it becomes disabled because it would require a careful code to
ensure that WC was only used in circumstances where the errata would not
matter...

Thank you! This has been plaguing us since 2.6.28, but all I can get
out of people is "no, it's doing the right thing, we can't satisfy your
request because handwavey errata stuff to do with conflicts, can't tell
you off the top of my head."
We want WC ioremap, and we try an MTRR in case PAT is disabled (because
of the errata that makes WC PAT sometimes give non-WC behavior). Give
us a mapping, whether or not it's really WC. Failing the mapping is not
OK.
