hang, no oops message or anything, it just stops

Well just after writing my last mail I had a short look at the driver,
and I think I have found some path from the driver initialization part
down to where the last messages are printed, but I hadn't time to add
printks or whatever so far. But thanks for the funtion name, I will pay
attention to it when I get to having a look at it.
A word to Keir's post: From my experimentation a week ago, I do
remember that some different IRQ was used for the S-ATA controller with
native linux vs Xen linux.
On another point, I don't know how much output I will produce (for my
two disks at two ports), but I doubt that it will fit my screen if I am
finally diligent in the driver :) So either I capture the log via some
serial port (if that is possible to do with just another PC next to it
and some cable) or via the kernel's net-log-facility, but that would
require it working before the initialization of the S-ATA controller...
ok I won't look at it right now anyway but if you have some links lying
around, feel free to post them ;)
(in case you should be interested, I just spend this weeks free time
participating in bwinf, "Bundeswettbewerb für Informatik", some German
informatics competition, and I have 3 class tests to do this week, so
maybe I get to it next weekend or so :) )

that sounds reasonable
