Re: rtai 5.0.1 freeze after rtai_sched.ko load

In your config I see a full enabling of the auditing options. 5.0.1 is a release done mainly because of having forgot to distribute README.CONF_RMRKS, which invites you  to disable them. Maybe the problem is not that but that has been verified to cause what you witness.
Moreover the  4 CPUs are all true ones, ot 2 true + 2 hyperthreaded? Get rid of hyperthreading.

Take into account that I've never seen yet interrupt number in the range of 33000. You are likely using MSI, try without such an option.

Subject: [Rtai] rtai 5.0.1 freeze after rtai_sched.ko load

Hi,

I try to install RTAI on ubuntu 16.04 and Intel(R) Core(TM) i5-2500 CPU @
3.30GHz

I used linux 4.4.43 fresh kernel with RTAI 5.0.1 patch.
When I load rtai_hal.ko I have got this dmseg :

RTAI[hal]: mounted. ISOL_CPUS_MASK: 0.
[  116.776943] SYSINFO - # CPUs: 4, TIMER NAME: 'lapic', TIMER IRQ: 33026,
TIMER FREQ: 102889999, CLOCK NAME: 'tsc', CLOCK FREQ: 3292491000, CPU
FREQ: 3292491000, LINUX TIMER IRQ: 33026.

When I try to load rtai_sched (for testsuite tests), the system freeze.

I attach my config file in this email.

Any idea ?

Best regards.

L.Pino
