I spent most of this past weekend trying to install an RTAI+comedi setup
on a new Linux box, and ran into an issue reported here a few weeks

This is on a Fedora Core 5 system using a vanilla 18.104.22.168 kernel and the
only 2.6.16 kernel patch included with RTAI 3.3cv. I was able to get
around the problem by downgrading to 22.214.171.124, and using the appropriate
patch for that kernel.
Some Googling around indicates this problem is related to a module

Potentially, this is only a gcc 4.0+ problem, as a colleague here had no
problems with kernel 126.96.36.199 + RTAI 3.3cv on a Debian (gcc 3.3) system.
However, I have no real idea about such things, so I can only guess what's
Is this something you guys can fix? My system is up and running, so it's
not a priority for me, but there's been a couple postings to this list
about it, and knowing what I know now would have saved me about a half
dozen kernel compiles... ;-)
