10.04 live cd no Realtime was created by blazedforever
I downloaded the 10.04 emc live cd and installed it seems the realtime system is not loading. I checked the grub boot menu and realtime kernel is listed but doesn't seem to load, the memory lock limit is set to 20480KiB. Here is the output i get running emc from term.

Have you tried doing what is suggested in the URL pointed to?
wiki.linuxcnc.org/cgi-bin/emcinfo.pl?LockedMemory
(Your second sentence suggests that you have, I am just trying to be clear)
Not that that should be necessary on a fresh, LiveCD install.

yes i have sorry.

limits.conf :
# /etc/security/limits.conf
#
#Each line describes a limit for a user in the form:
#
#<domain>        <type>  <item>  <value>
#
#Where:
#<domain> can be:
#        - an user name
#        - a group name, with @group syntax
#        - the wildcard *, for default entry
#        - the wildcard %, can be also used with %group syntax,
#                 for maxlogin limit
#        - NOTE: group and wildcard limits are not applied to root.
#          To apply a limit to the root user, <domain> must be
#          the literal username root.
#
#<type> can have the two values:
#        - "soft" for enforcing the soft limits
#        - "hard" for enforcing hard limits
#
#<item> can be one of the following:
#        - core - limits the core file size (KB)
#        - data - max data size (KB)
#        - fsize - maximum filesize (KB)
#        - memlock - max locked-in-memory address space (KB)
#        - nofile - max number of open files
#        - rss - max resident set size (KB)
#        - stack - max stack size (KB)
#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit (KB)
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
#        - msgqueue - max memory used by POSIX message queues (bytes)
#        - nice - max nice priority allowed to raise to values: [-20, 19]
#        - rtprio - max realtime priority
#        - chroot - change root to directory (Debian-specific)
#
#<domain>      <type>  <item>         <value>
#

#*               soft    core            0

I updated the rt kernel via synaptic thats why the version shows as realtime-2.6.32-122-rtai, had the same error before the update.

I am not sure that the format "* - memlock 20480" is valid, it doesn't match the file comments.

I wonder if it is worth trying

* hard memlock 20480
( and possibly also * soft memlock 20480 )

Ignore that, linux.die.net/man/5/limits.conf says that "-" means "hard" and "soft" at the same time.

Bugfixes don't happen automatically for problems not seen by the developers. It might be worth adding a bug report at
sourceforge.net/tracker/?atid=106744&group_id=6744&func=browse

Is the problem with existing configs, or do the sample configs not work either?

Sorry
I have alread reinstalled back to 8.04
It's running on an old 650mHz pentium with 320mb


I installed new from CD, than updated via www.
same to emc2 .4 = latest
Tried to runt he sim-axis-mm No startup.
No emc but rtai .... errors ...

Decided too hard problem for me to solve


Tried to see the second parport... also no succes, but wrong-directory errors from manifacturers CD.
decided to solve one problem by the other = reinstall... Maybee PC is too old for 10.04..

Sorry


P.S.
In the moment I'm trying to get a second (cheep china ) parport running, for a luxury jog whell .
I wan't to have A / B, 4 axis and 4 speed buttons as inputs and 4 led's as choosen-axis- feedback.

did you check dmesg for any (maybe related) error messages?
