It most certainly is. It can be the result of a very high interrupt
latency at the wrong time, a kernel crash just at the wrong time, or
something else making the PMU unhappy...
Are you guys all confirming that the problem happens on a kernel without
CONFIG_CPUFREQ enabled at all ? Have you tried also doing (as root)
echo "0" >/proc/sys/kernel/powersave_nap
That will make the machine hotter & suck more battery (at least on
machines where nap mode is supported, that isn't the case of the
wallstreet in the first place) but it may be a good indication if that
fixes the occasional shutdown.
