Re: CPU hangs on Celeron

Thanks for the 32 bit test, but it must work also 64 bits. Nowadays I'm developing RTAI mostly using a 64 bit PC, checking it afterward on a 2 CPU SMP 32 bits PIII, gcc 4.3.
Therefore there a, extended soft/hard compatibility time lapse should be still be maintained by RTAI, the only thing needed being a TSC.

Hello!

1. Thanks for your help!

2. I use x86_64 kernel setting.
Linux runs smooth so I think its good for the Celeron 1020E.

I will try 32bit Celeron the next days and also try RTAI 5 if it is
released.

Thanks again!

Best regards,
Christoph
