This sounds like the driver specifics I was talking about.  ASoC doesn't
get involved in anything that's likely to affect memory much in a way
that'd only show up on one system, and I'd expect things that did go
wrong to have a much less specific effect.  It could possibly be the
generic AC97 bodge (at which point it's specific to ac97.c) but it's
unlikely to be ASoC itself.
