The reason I ask is that the stuff which is going wrong is the stuff
which requires two fetches from the drive registers. Could that be a
caching bug (eg caching it, prefetching and thus reading a register too
many times etc) - it seems more likely than the drive given that nobody
else is seeing anything like this.
