[Bug 290498] Re: linux-rt restricted to one CPU

[Realtime Dutchman]

Mike,
 
I installed the official jaunty 9.04 release and don't see any improvements concerning CPU performance. It still is very slow, asking to much time from my cpu and the strange thing is that when I install jaunty on a dual core pc (Intel cpu) it appears to be very unstable but I don't see the delays. Even during installation I had a system hang/crash which resulted in doing the installation all over again.
After googling I found out that I'm not the only one having this nasty issue.
Last night I gave up using the official  ubuntu 2.6.28-3-rt kernel and compiled my own from the www.kernel.org site. 
 
I used info from the following web page :
https://lists.ubuntu.com/archives/ubuntu-studio-users/2009-May/004757.html

and the Debian tutorial how to build a kernel. 
It took almost three hours before the pc had ended its complie and linking actions but finally I was able to generate to installation deb. files for kernel 2.6.29.3-rt13 which is running on my pc. 
I still see delays on my single core so that one seems not to be resolved but I hope this kernel will run on our dual core (It should if have read the comments well about this issue).
