Dear list,

I am testing Xenomai 2.6.0-rc4 on a 2.6.38.8 linux kernel. I have two cards,
one NI 6713 for AO and one NI 6143 for AI. I use the analogy_ni_pcimio for
both, and it loads well. I can run the config program succesfully too.

If I remove the devices using 'analogy_config -r ...', then unload the
modules with:

rmmod analogy_ni_pcimio analogy_ni_mio analogy_ni_tio analogy_8255
analogy_ni_mite xeno_analogy

then load them again and try to reconfigure, I get the following error on
dmesg (I include the boot messages and the execution of a "cmd_read"):

[   55.735198] Analogy: analogy_ni_pcimio: pcimio_attach: found pci-6713

[  251.563830] Analogy: a4l_request_irq: IRQ registration failed

BTW, the analogy_config program does not report those errors.

This is bothering because I'm fiddling with the drivers and everytime I
change something I have to reboot. Anyone experiencing the same problem?

Thanks for your help,
Fernando

Sorry. I will try to fix that as soon as possible.
