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.
Seems like somebody is stomping out
dev->transfer.irq_desc.rtdm_desc.flags between attach and detach (flags
and all fields in its vicinity is zeroed out), hence the interrupt is
never removed from the interrupt handler tables wreaking havoc with the
entire kernel.
Alexis.
