Hi, I made some tests and find out following: Driver doesn't freeze computer, but effectivelly lock it when card is plugged - looks like some loop without return. Card's led is lighting green. After removing card from slot I gets this in dmesg: pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) DVB: registering new adapter (pluto2). pluto2 0000:03:00.0: board revision 15.255 pluto2 0000:03:00.0: MAC ff:ff:ff:ff:ff:ff pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2: could not attach frontend pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) pluto2 0000:03:00.0: overflow irq (1) Michal
