I did some more testing, and on my X61s laptop, using a somewhat more recent snapshot (v2.6.26-rc1-434-g9662369 from Linus's tree Sunday morning), I was able to reproduce the failure after a suspend/resume without nopat, but after adding nopat, the problem seems to have gone away. I'll do some more testing, but it looks hopeful that this might be another manisfestation of http://bugzilla.kernel.org/show_bug.cgi?id=10620 and booting with nopat works around the problem. - Ted
