Hi Paul, > > Perhaps you might want to have a look at this thread, about RCU stalls > and a possible common root cause for some of them. > > http://marc.info/?l=linux-rt-users&m=136258510132233&w=2 Thanks for the information. However the application is intended to run with 100% CPU (real time) load on one core. That's why the CPU core is isolated for. They are reserved for this application. However to keep a system stable, the RCU must still run on this very core. The one option is to raise the prioriy of ksoftirq (which contains the RCU stuff (if I know right...)) or I was playing with the RCU_BOOST feature which I expected to have the same effect. However, the RCU_BOOST feature is not clear to me as I still saw the kernel messages about RCU stalls that I did not want to see anymore...
