UbuntuStudio 8.10 multi cpu suggestion

[Ouoertheo]

I just wanted to let the ubuntustudio 8.10 users know that in the default kernel (2.6.27-3-rt) there is no support for multiple cpus as of this moment.

You can check to see if this is your case by checking the output of-
dmesg | grep "CPU"

If it states that only 1 cpu is being used, then you should switch back to the kernel version 2.6.24-23-rt.
This way you won't have to reinstall ubuntu if you want that extra boost.

Since I upgraded, and didn't do a clean install, my old kernel was already there (or is it installed by default?) and all I had to do was boot from it and reconfigure some xserver/video card stuff.
If that's not your case, then you should be able to find the kernel and headers by doing a little digging.

Indeed a known (and serious) issue, track it at launchpad:

https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/290498

not sure what the status of the bug is (what exactly causes it, does it also affect upstream, etc) and whether anyone is working on it.

It will not be worked on, since Jaunty is already in active development. If 2.6.24-rt works for you, use that, if (like me) you're on a fresh install, then best to wait for Jaunty for now. Or reinstall Hardy, it IS LTS, after all.

Both of mine are running. Ubustu Intrepid here.
