I'm using a model name : Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz and can confirm some problem with power down, at least in 2.6.38.2. Sometimes I only see the powerdown message but the machine will stay on (and the fan starts getting louder). But in contrast to the above description (that commit seems to have been already included in 2.6.37), I never had a problem with powerdown with a kernel <2.6.38. I have CONFIG_X86_ACPI_CPUFREQ enabled, but I currently can't offer much more insights, because I haven't tried to analyze that problem. The problem doesn't appear with any shutdown, and I don't know (and can't remember) if that already happened with 2.6.38. Besides switching from BKL to non-BKL, I haven't changed the config when I've switched from 2.6.37.x to 2.6.38 (other than what make oldconfig does). Maybe it's a totally unrelated problem, but I thought it might be good to mention that I'm having a problem with powerdown in 2.6.38 too.
