Hello. I've recently upgraded the kernel on my RH9 machine to 2.6.0-test3.
Everything is working now except lirc. I have a homebrew serial receiver
and use the lirc_serial module. I got a patch for 2.6.0 from
http://flameeyes.web.ctonet.it/ to add lirc support to 2.6. The module
loads fine, but when I run the mode2 userspace program, I get this in my
syslog:
