Hi, just found that

echo 0000:06:01.0>  /sys/bus/pci/drivers/analogy_mite/unbind

does not do the same thing as

analogy_config -r analogyN

in fact it leaves the system in a state where using the driver results
in a kernel OOPS.

Will try to look into it further tomorrow...

OK seems like we have some interrupt cleanup problem, the following command
sequence:


OK thank you for the report. I did not have time to look at it yet but
that will be done soon.

Is it blocking for you?
Yes, and even worse is this problem:

# /usr/local/sbin/analogy_config analogy0 analogy_ni_pcimio 6,1
# /usr/local/sbin/analogy_config -r analogy0
# cat /proc/xenomai/irq
Killed

I was looking into it last week, but is a workshop since monday, will get back at this tomorrow.
