Different problem; Xenomai wouldn't start: I-pipe: could not find timer for cpu #0 dmesg: http://www.zultron.com/static/2013/01/xenomai/3.5.7-test/foo-dmesg-3.5.7.log .config: www.zultron.com/static/2013/01/xenomai/3.5.7-test/foo-kernel-3.5.7.config FYI, I found this same problem on two of my systems while testing your Debian packages. Both AMD Athlon II 64-bit (one single, one dual core). They're about the same generation of motherboards, AM2 or AM2+ socket. One is AMD 770 chipset, the other NVidia GeForce 6100 / nForce 430. Hardware looks similar to Mariusz's in this post, where he had the same problem: http://www.xenomai.org/pipermail/xenomai/2012-December/027121.html He's also running AMD 64-bit on a Gigabyte motherboard, but the next generation AM3 socket, Phenom CPU, AMD 890 chipset. I don't have a C1E BIOS option on these boards to enable/disable. These same motherboards don't suffer this problem with mainline Xenomai on 3.5.3. >> 2) posix/mprotect is failing: "FAILURE: sigdebug_handler triggered, >> reason 2 memory write after exec enable". > > > I guess you need Jan's fixes. Jan's fix is to turn off CONFIG_TRANSPARENT_HUGEPAGE, right? I'll report back after a new 3.5.3 kernel is compiled. >> 3) FPU warning: "fptest.h:24: Warning: Linux is compiled to use FPU in >> kernel-space.

So, here you say it's harmless, is that right? http://www.xenomai.org/pipermail/xenomai-core/2009-05/msg00011.html John _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
