[mythtv-users] LIRC: lirc_serial irq busy at boot, how do you load the module

[David Krainess]

Hi all,
OK, installing Fedora 20 and trying to get current with MythTV.  I can only get the lirc_serial working manually from the terminal, and am wondering how to get it working in the automated startup.  If I "modprobe lirc_serial" myself, everything works.  
/etc/modprobe.d/lirc.conf
options lirc_serial irq=19 io=0xe880install lirc_serial /bin/setserial /dev/ttyS2 uart none ; /sbin/modprobe --ignore-install lirc_serial
/etc/rc.d/rc.localsetserial /dev/ttyS2 uart nonemodprobe lirc_serial
# dmesg|grep lirc[    4.888182] lirc_dev: IR Remote Control driver registered, major 247[    4.967296] lirc_serial: module is from the staging directory, the quality is unknown, you have been warned.[    4.967780] genirq: Flags mismatch irq 19. 00000000 (lirc_serial) vs. 00000080 (serial)[    4.967969]  [<f7e9ff90>] ? rbwrite+0x90/0x90 [lirc_serial][    4.967976]  [<f7e9f994>] lirc_serial_probe+0x44/0x340 [lirc_serial][    4.968015]  [<f7ef111b>] lirc_serial_init_module+0x11b/0x1000 [lirc_serial][    4.968128] lirc_serial lirc_serial.0: IRQ 19 busy[    4.986061] lirc_serial: probe of lirc_serial.0 failed with error -16[    4.986379] platform lirc_serial.0: lirc_dev: driver lirc_serial registered at minor = 0
unload and reload works...
# modprobe -r lirc_serial[  284.123459] lirc_dev: module unloaded
# modprobe lirc_serial[  294.151195] lirc_dev: IR Remote Control driver registered, major 247[  294.162184] lirc_serial: module is from the staging directory, the quality is unknown, you have been warned.[  295.032030] lirc_serial lirc_serial.0: auto-detected active low receiver[  295.032202] lirc_serial lirc_serial.0: lirc_dev: driver lirc_serial registered at minor = 0
Any advice to solve, I've tried swapping slots and can't change the IRQ on the serial board?  Thanks in advance for any help.
