Thanks guys!
@Raffaele: that's great, didn't know there were more recent rt-kernels for
debian. I have a 32bit machine, so I'm going to try this one:
http://packages.debian.org/jessie/linux-image-3.10-2-rt-686-pae
I have an nvidia driver (sigh), I guess it's likely that rt-kernel is not
going to like it. I read I could patch some nvidia stuff into the
rt-kernel, but that's another story. I'll try this first.
@Emiliano: yes, I do set the governor to "performance" when I need it. I
also wondered, maybe it could also be a faulty firewire cable causing the
random freeze?
Is the D-Bus enabled an annoyance to low-latency processes?
thanks again,
cheers,
M
