I have the same modules except 'rfkill'

Same result for the modinfo.

-----

So the first time I run:

[mark]
nfctool -d nfc0 -p
Start polling on nfc0 as initiator

With an error in syslog/dmesg:
nci: nci_ntf_packet: unknown ntf opcode 0x0

The second time:

nfctool -p -d nfc0
Protocol error

With an error in syslog/dmesg:
nci: nci_start_poll: failed to set local general bytes

Then I do:

nfctool -0 -d nfc0

it returns to point [mark]
