CentOS - Sep 2009 - Quo vadis?

Hi,

In the course of my experiments with rt kernels
it so happens that the gui versions of tuna built
from upstream (RHEL, F11) SRPMs show wrong affinity settings
for IRQ threads.

Where would be a proper place to report this
and get some help on other rt-related issues?

Thanks,
Sasha

It wasn't actually a tuna bug but rather misunderstanding on my part.
When tuna-0.8.4-1 gui is being used to set IRQ affinity
it also changes affinity settings of a related kernel thread.
On the other hand rtctl-1.5-1 script can only restore
kernel threads affinities. The following rtctl-1.5-1 patch
may be used to restore IRQ affinities on system startup
according to affinity settings of related kernel threads if needed:
