It is probably the most interesting to play with. ;) It plugs somehow weirdly into the slot. I somehow have to push it in and a little bit pull out so that some mechanical lock catches the card. But, it allocated resources only once, and in other cases the driver is somehow locked up. It could be a driver issue but I think it is interesting information in this moment. Below I leave always 3 empty lines to emphasize I was pulling out the card and after a while back in (like in previous attempts). The output is just the one from dmesg, it is more detailed then what is logged through syslogd.
