When was the last time you tried it? It should work
on amd64 and PPC.
You might need to disable high res timers.
ive tried a few times most recently patch-2.6.13-rt4 - its never worked..have messed
around with timer resolutions and 'generic x86-64' vs 'amd64' settings as
well. it reboots right after grub loads the kernel, so fast that you cant even read what
it says (if anything).
thats with 'Complete Preemption (Real-Time)' . the 'Preemptible Kernel
(Low-Latency Desktop)' option fails to compile:
In file included from arch/x86_64/kernel/mce.c:17:
include/linux/fs.h: In function `lock_super':

make: *** [arch/x86_64/kernel] Error 2
the similar (same?) 'Preemptible Kernel (Low-Latency Desktop)' choice in vanilla
sources compiles but is grossly inadequate, even with a generous 256 buffer jack is full
of dropouts with even basic usage. its no big deal, im happy to boot into XP for the few
occasions i need to make/record music, plus it will be decades before Samplitude runs on
Linux or ardour or anything else 'free' catches up to it or Ableton-Live in terms
of usability/flexibility/fun-factor...
