I'm getting a double fault in a disk driver that I am building. I'm
working on more detailed debugging.
From a bit of archive reading, it appears that a double fault is
classically a stack overflow. However, the stack that the double fault
is reported on is clearly not overflowed. The resulting back trace is
actually very reasonable.
What other problems should I be looking for in determining the cause of
the double fault?
A few more details. This only happens at boot time and is 100%
reproducible at the same location every time.

ps
Sorry, I can't post the actual back trace due to license restrictions
(please draw your own conclusions. :-)
