Is this related to HEAPSZ or STACKPOOLSZ? My mind is getting foggy about all the things I've seen, but it seems like it was happening earlier in the tests until these config values were quadrupled. 2) posix/mprotect is failing: "FAILURE: sigdebug_handler triggered, reason 2 memory write after exec enable". 3) FPU warning: "fptest.h:24: Warning: Linux is compiled to use FPU in kernel-space. For this reason, switchtest can not test using FPU in Linux kernel-space." Regression test run log: http://www.zultron.com/static/2013/01/xenomai/foo-xeno-regression-test.log Log of dmesg with oops at end: http://www.zultron.com/static/2013/01/xenomai/foo-oops.log Kernel .config: www.zultron.com/static/2013/01/xenomai/foo-kernel.config The kernel is built from the elrepo.org kernel, and this config file overrides the upstream config; makes it easy to see the Xenomai-specific changes: https://github.com/zultron/kernel-ml/blob/branch3.5.3-xeno/config-3.5.3-xenomai-x86_64 Any help is greatly appreciated! These RPMs are part of my effort to enable RH-like distros to run LinuxCNC and expand the pool of potential users, so if I'm successful, many folks will benefit. John
