Sorry I haven't answered before, I've missed your mail in my inbox :$ I have checked that kernel parameter using 'sysctl -a | grep iso', but haven't find such option. Did I searched what you asked?
I'm more fan of K stuff, but currently I use E17 compiled by myself, login using KDM. This setup has been the same for the last 5 years at least and I never used affinity for any of them. At this moment I've hacked my system using a cron entry that changes all processes affinity to 'f' every minute. I'm kind of lost with this :S 2012/5/2 Ben Hutchings <[email protected]> > On Wed, 2012-05-02 at 20:21 -0300, Wido wrote: > > Hi again, > > > > > > Ok, I can confirm this is recurrent.
