Of course you're welcome to do that. Or if you like, you (or I) can
copy the information to the xenomai.org wiki and the linuxcnc wiki can
point to your page.
I'm hoping that someone else will volunteer to take over package
maintenance once the dust settles a little. That will be a while, but
if you're interested in hosting the package repos on xenomai.org
eventually, moving the wiki material there makes sense.

Great! I'm working around this for now by packaging Jan's smictrl
utility. That could actually be sufficient; I'd rather put effort into
a more user-friendly wrapper, and maybe a config file and init script
for persistent settings across reboots.

This affects RedHat-like distros, which turn this on by default in
package builds. My RPM packages (forthcoming) have a workaround, so
low-priority for the packaging effort.

Great. On my test machine (1.7GHz Celeron), 200 would have been 2x
enough. Michael saw this problem on his machine too, but I didn't see
his numbers.
Thanks for the support Gilles. I think this will help the community
greatly, and hopefully reduce the support headache for developers at the
same time!
