<heh> Yeah, I just figured out trying to manually apply the patches today that I need to use a realtime directory of "linux" for the PREEMPT_RT version and that rt-linux is different from linux-rt <sigh> > Would you mind pasting the messages indicating that rt-preempt is > detected? I'll have to re-create that. I've blown away and re-started from scratch several times now. IIRC, there was a configure step as part of grabbing the Debian build-depends that recognized the linux-rt kernel. I then stumbled on trying to find the rt-linux directory (see above) and headed off in a different direction (trying to apply Michael's patches to HEAD). >> What kernel(s) and arch(s) are you trying to work with on the >> Fedora side?

I'm using amd64 as well, but am currently with the stock Debian 3.2.0-rt kernel. I'm hoping to get a usable system (with hardware help for motor control, no bit-banging the parallel port) with a mainline kernel. I think if any sort of workable system will run on an -rt kernel it should be pretty straight-forward to migrate between any of the available versions (2.6.x, 3.x). > I'd be happy to supply you with what I have so far.

That would be GREAT!
