ipipe crash when trying to isolate cpus #13

Closed steffenmauch closed 10 years ago

steffenmauch commented 11 years ago

Due to some problems with the latency, I tried to use isolcpu to achieve better latency results. I set noirqbalance during boot time and then used the script inside README.ISOLCPUS.

The following crash is the result! foto 05 08 13 09 07 47

As kernel I use: Linux rtai-fpga 3.8.13-RTAI #4 SMP PREEMPT Sat Aug 3 12:04:41 CEST 2013 i686 i686 i386 GNU/Linux

gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

Please base your kernel configs off the the ones I have provided. If the issue persists, post a new screen shot of the problem.
