I have an Atom 2800 motherboard system running 10.04 and 2.5.2 freshly

generated by Stepconf Wizard and only minor tweaks to make estop work. This
problem also happens when I try the sim/axis and sim/tklinuxcnc configs.
Sometimes Linuxcnc comes up and runs fine, but about every second or third time
I launch it, I get this error: http://pastebin.com/LSJGvCJX ([EMC]DEBUG =
0x7FFFFFFF). If I just dismiss the error and launch again it comes up fine.
I tried this on identical hardware set up that I dd'd this build and
configuration to and it happens there as well.
Weird!
The first thing that comes to mind is a startup race condition.
Can you build linuxcnc from git on this machine? If so try the attached
patch (against the current head of v2.5_branch) and pastebin the output
from a successful and failed launch. If not, let me know and i'll build
a deb for you.
