great list!
I have had this error popping up all the time since I upgraded to the 10.04
distribution ( seldom on the 8.04, same computer)
and the isolcpu=1 seems to have solved it...
does it follow then that the second cpu in this case is not being managed by
the realtime kernel?
I am currently running my emc on the second core 'taskset 2 emc ***.ini',
and it seems impervious to the dreaded error message, regardless as to what
else I run on the machine...
but am I safe in running this way? am I still getting realtime performance
on the core that has been isolated on bootup?
thank you to all the contributors!
