ubuntu10.04 Lcnc 2.7 rtai error

The J1900 have a wrong ram because not start at all.

Instead I try with H97M gigabyte and I3 3Ghz 4° gen.
All ok .... whit any type of trik on rtai and cpu, withous disable sometings from bios, whit 6 glgears whindows and 2 firefox youtube open after 2 hour obtain

servo thread 1ms 10580

base thread 25usec 11900

I think if I block 1 CPU for linuxcnc an disable any things from bios all system work perfectly .

No see at all rtai error message. ..... Ubuntu 10.04 linuxcnc 2.7

IMHO

I would toss out Ubuntu 10.04 as its no longer maintained and use Wheezy

I would not bother with isolcpus at all as it will just slow the system down to gain a few usec better latency

With hardware stepgens and servo systems, any latency in the 0 to 50 usec range is absolutely fine,
there is really no point in getting better (and up to 500 usec can be OK with the right hardware setup)

OK message receipt but isolcpu I think it's useful if you want to run other programs at the same time to LinuxCNC ... or maybe this is a mistaken belief ?


and disable any thngs not seccesary by bios is a good things or not? ....

If I start from minimal installation of ubuntu 12.04 it may be advisable use it instead of debian?
