In order to get the current git tip of Xenomai 2.6 running over non-core ipipe patched kernels I had to apply the attached patch. Now the code it patches is not in 2.6.1, but it might be related to the same IPIPE_CORE_APIREV checks, which in my opinion are not very clean in the current code. > > The things I would try to debug this issue: > - add some printks along the xenomai initialization to see what function > exactly is causing the issue (the usual suspect would be rthal_start_timer) > - try and enable the APIC or I/OAPIC nmi watchdog, so that it can tell > you where the lockup happens > - try 2.6.0 (which likely does not work either) > - if 2.6.0 does not work, try a "git bisect" between 2.5.6 and 2.6.0 > - if 2.6.0 works, try a "git bisect" between 2.6.0 and 2.6.1 > > On my side, I will try and use your kernel configuration on my atom, to > see if I reproduce the issue. > > Regards. > > -- > Gilles. > > _______________________________________________ > Xenomai mailing list > Xenomai@xenomai.org > http://www.xenomai.org/mailman/listinfo/xenomai -------------- next part -------------- A non-text attachment was scrubbed...
