Subject: RE: [Emc-users] Home to index triggers following error
The machine is currently running Linuxcnc 2.7, but the Mesa cards, are
significantly older, dating back to the Linuxcnc 2.5 era.
I'm not sure how comfortable a feel about updating this machine to current
at the moment. It is running 32-bit RTAI, and I'm not confident I'll be
able to achieve the necessary latencies with the currently available
mainstream 64-bit real time kernels required for the current version of
Linuxcnc on the machine's current computer.
All of my actively running Linuxcnc machines are still on 2.7. I am in the
midst of a major overhaul of one machine that will be current version of
Linuxcnc. But I'm very hesitant to pull the other running machines out of
production to upgrade until after I have more experience working with the
newer versions. (JA and the move to requiring 64-bit kernels were very big
changes.)

Yeah, its not a firmware issue so the old cards should be fine,
but the driver fix is only in 2.9. Theres no specific reason the
(one line) fix could not be applied to 2.7/RTAI except I dont
have a build environment for that anymore.
