I'm using a simple hardware serial port receiver as well. Not only
that, none of the potential issues with the serial port uart are an
issue for me as I have the SERIAL_8250 disabled in my kernel
altogether. All the lirc stuff is compiled in as well...no modules
involved at all. What's ever more perplexing is the fact that mode2
works with the default driver and /dev/lirc0 that I'm using, which
rules about everything except something breaking the decoding. That
would seem to be an issue with the ir-lirc-codec. That's used by the
serial_ir but wasn't needed for lirc_serial.

There were even several bugs around just that in ir-lirc-codec.c, all
of which I've patched into the kernel, and still no luck. Just
horrible.
