I don't have any trouble with rt kernels when not using a proprietary
(ATI) driver, excepted of jitter for external MIDI. Most times the rt
kernels are as stable as the latest Atari ST TOS on my machine.
Something I never would have guessed :). The proprietary driver for my
ATI graphics doesn't work at all :(.

This might depend on how well the applications and libs fit together. I
guess for Suse upgraded to the most up to date Linux software this is
most probably, while for 64 Studio, were everything is tuned by default,
but also very often outdated, rt kernels seldom cause troubles. For my
64 Studio there's one exception. I run Qtractor (svn versions) and
Qtractor isn't included to 64 Studio at all. Qtractor often crashes
because libfluidsynth isn't a good version for DSSI usage with Qtractor.
From my experiences it doesn't seems to be the rt kernel, but bad tuned
applications and libs, that's why I changed from Suse to 64 Studio. 64
Studio has some disadvantages, for Suse it's possible to run 32-bit
applications on a 64-bit Suse, e.g. LightScribe software, it's
impossible to do that on a 64-bit 64 Studio. For Suse it's possible to
run completely new applications without any effort, while it's
impossible for 64 Studio.
Such rt kernel trouble seems to depend to the tuning of the installation
and seldom to the kernel itself. YMMV.
