[Ardour-Users] Hardy or Jaunty

[Kees van Veen]

I can confirm this, had serious trouble with high cpu loads (and xruns) 
with the rt kernel that Jaunty ships with, while with Hardy I didn't 
have these problems. I upgraded because of jackd which is vs. 116 in 
Jaunty, Hardy has 109.

I 'solved' it by installing 2.6.29.1-rt8-custom as mentioned in 
https://bugs.launchpad.net/ubuntu/+source/linux-rt/+bug/366352 
(downloaded the one from Travis Carter). Running fine with that kernel now.

Regards,
Kees

The rt kernels in Jaunty are seriously broken (or they were when I tried them anyway) and do not work at all on mutliprocessor machines. It's not an Ubunutu-specific problem, there were simply serious issues with the rt-kernel patch at that time.
