Especially buggy steppings of C3s would stop snooping while in 'hlt', so
it wouldn't surprise me if they stopped while doing a speed transition.
In the former case
flushing and disabling the CPU caches ought to be sufficient.
Sounds reasonable, unless that causes problems of its own. (My general
experience with Via CPUs is that doing anything even slightly unusual
will result in strange behaviour or outright buggyness.)
