Re: kernel tainted/device busy for ttyS1?

[John B. <ire...@gm...>]

Thanks! I don't think I should be playing around with ttyS0, since that's
got a serial cable that's been changing channels just fine on my set top
box.

Would I put this in /etc/modprobe.d/lirc? (And would /etc/init.d/irda-utils
or /../irda-setup play into this at all?)

Thanks again!
