Ubuntu Bugs steppgen in 10.04
You could try isolcpus, that normally leads to some improvement in latency, though that seems unlikely to be a real fix of the underlying problem.
Instructions here: www.linuxcnc.org/component/option,com_ku...0/lang,english/#6955
Is this a software-stepping machine? If you are using external hardware (Mesa, Pico, Pluto) and have no base thread then 60uS might be borderline acceptable. If you do have a base thread and are using software signal generation then the problem does need solving.

isolcpus tip did not help to better latency...
Instalation v10.04 is new from liveCD no upgrade.
yes, I using MESA boards.
The all machines have stepper motors.
The basic question?
why 8.04 work -> 10.04 not work
I tried basic config "hm2-stepper" and still error "join x following error"
EMC2 ver 2.4.6 is better than master 2.6.pre-0
Thx for all help

I have always used master on 8.04 for testing on my little mill.
At some point something changed as now I can't even jog it far without it follow erroring.
The big problem is I'm, not sure when it changed. i hadn't tested in a while.
using mesa 5i20 boards hardware steppers.
I guess I should try using 2.4 see if there is a difference.

You are using Ubuntu 8.04 and EMC> 2.5?My case is a little simpler.
