I've been searching all over and found many posts but no solutions
that have worked from me.
Yesterday I merged my mythbackend with my file server and I have
everything working except for my homebrew serial blaster is not able
to send.
It worked with my previous machine kernel :
Linux mythmaster 2.6.30-gentoo-r5 and lirc 0.8.7

it is not working with the new machine kernel:
Linux mythmaster 2.6.39-gentoo-r1 and lirc 0.9.0

lirc configure:
./configure --with-transmitter --with-driver=serial --prefix=/usr
--enable-debug --with-x

dmesg:

serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
lirc_dev: IR Remote Control driver registered, major 61
lirc_serial: in init_timing_params, freq=38000 pulse=3368, space=3368
lirc_serial: auto-detected active high receiver
lirc_dev: lirc_register_driver: sample_rate: 0

modprobe.conf
options lirc_serial irq=4 io=0x3f8 debug=1
install lirc_serial setserial /dev/ttyS0 uart none; modprobe
--ignore-install lirc_serial

lircd start command:

 /usr/sbin/lircd -P /var/run/lircd.pid --device /dev/lirc0 -d
/dev/lirc0 --output=/dev/lircd

irsend results:

buffer: -BEGIN-
buffer: -SEND_ONCE DCT2000 1-
buffer: -ERROR-
irsend: command failed: SEND_ONCE DCT2000 1
buffer: -DATA-
buffer: -1-
buffer: -hardware does not support sending-
irsend: hardware does not support sending
buffer: -END-

messages from the command above:

Jun 10 08:38:04 mythmaster kernel: lirc_serial: Interrupt 4, port 03f8 obtained
Jun 10 08:38:04 mythmaster kernel: lirc_serial: freed IRQ 4

I'm really at a loss, I have tried everything.  Let me know if there
is anything else that can help.

Thanks,
Lee
