Thanks for the links! I hope you enjoy your vacation nevertheless ;-)
I don't use yaourt to build linux-rt. But I tried the binaries: the same
problems occured. I had a bunch of xruns as soon as I started playback, on
a session which runs smoothly with other kernels. I could restart Ardour
and reproduce it so it's not just an occasional mishap.
I also tested with the option for i915 do_wbinvd=no which helps other
people (see https://aur.archlinux.org/packages/linux-rt/). But no
improvement for me.

Indeed, I should do that. Thanks for pointing to that list.

Cheers,

Much better would be to install the devtools package and build it in a
chroot, with "sudo extra-x86_64-build".

You could also try the following binary packages that I just uploaded
to see if that makes a difference:

Finally -rt is an experimental patch and folklore is that it stabilizes
somewhere around -rt10 or so :) =C2=A0I love computer fol=

Maybe it would be better to report
