There ARE problems:
1. Compiling Nvidia drivers. Fix was posted but one must do this manually
editing the Nvidia source code.
2. 2.6.26rt was unusable because of timing problems on one of my ide
channels. This may be hardware/cables/power supply related but the 2.6.23rt
works better. The problems was present in 2.6.25rt as well, though I do not
know if the rt-patch is the culprit. No one seems to complain about the
unpatched versions.
3. nted hangs up on exit in the 2.6.26rt!!! (Cairo/Pango). Works fine in
2.6.23rt. What rt has to do with anything here is beyond me and maybe the same
thing would occur in a plain 2.6.26.
I will try 2.6.27 when I have a patch, but 2.6.26 was a no go from the start.
Hi you all,
I can't understand that:
"[...] So, why hassle around and make a realtime kernel available in the
repositories if Debian can work on making other security and stability
related issues better?"
what's the relationship between (realtime) and (security or stability)?
If you plan to use a realtime kernel surely you do not want to boot it on a
production server (my belief).
To me applying an RT patch implies you want to stress your box to achieve
extremely low latency paying a certain price in terms of "stability" for
other non-audio appz.
Platforms: http://www.kernel.org/pub/linux/kernel/projects/rt/
these are the offical Ingo Molnar RT patches, never saw platform related
ones and never read about they will ever be
Hardware: RT patches add features to the kernel and without touching the
rest of the code, so an RT kernel supports the same hardware of a generic
one.
Disadvantages: compile an unbootable or nonworking kernel is a little bit
simpler :-)
cheers
