I ran into that one last night. I *think* I know what the problem
may be. My message is a little different. I got a "File not found"
error when the backend was starting up.
By looking at the logs ans scanning the time that the entries were
logged, I figured out that the kernel modules were not loaded when the
backend was starting. I was loading the modules with modprobe in
rc.local, which is executed after the backend startup script is executed.
I put the modprobe command in the mythbackend startup script,
which is icky. I believe that has fixed the problem, though I need a
few more reboots to make sure.
There has got to be a better way to do this. Anybody have any
