Hi,
No other process using gpib. The board is an original NI pcII. It is
configured in pcII mode using 7210 mode. Base address is configured to be
0x2b8 interrupt line 3 and dma 1.
Some information that might be interesting:
/proc/ioports before loading module pc2-gpib.o:

Loading the module I get:

ioports and interrupts remain the same.
On /var/log/syslog I see:

As you can see iobase isn't freed. lsof says that nobody is accessing

Hope this helps. Have I missed something?
Thanks for your time.
