Ok - thanks for the dmesg output and log. I suspect you've already
tried cycling power on the machine (If not, please do).
I have no idea what M$ XP was doing that might "fix" the problem.

I was just suspicious of our byte accesses to the same dword.
To answer you previous question, it's possible that M$ only
uses dword accesses. I don't know.

excellent - sounds like you are making forward progress even
if we can not reproduce the problem...worst case other users
(or customers) have a "work around" :^/

thanks,
grant

ps. I'll be unavailable until this weekend when I want to look at
the old and new logs a bit more.
