[Bug 659449] [NEW] lirc_it87 module does not create /dev/lirc0; causes a kernel soft freeze on remove

[Matti Airas]

Public bug reported:

I have an Asus EeeBox EB1501 (European/Asian variant), which has an
integrated IR receiver. On Ubuntu 10.04 (2.6.32-24-generic kernel), it
worked fine with lirc_it87 module and instructions from [1]. On Ubuntu
10.10 (without lirc-modules-source), /dev/lirc0 won't get created.
Furthermore, when doing "sudo rmmod lirc_it87", I get a soft kernel
freeze.
