Hmm, maybe related: Philippe, I once posted you an oops under qemu-system-x86_64 which we explained with a probably broken toolchain. I just pulled out that config again, updated everything (crosstools-0.43: gcc-4.1.1-glibc-2.3.6-tls + tiny patch [1], Xenomai trunk, adeos-ipipe-2.6.19-x86_64-1.0-06) - and still got that crash on "latency" startup. The oops still happens around [2]. Interesting is that turning off CONFIG_XENO_OPT_SCALABLE_SCHED makes it go away. Given that I now tested my setup with gcc4 (instead of the earlier gcc3 run), there may be some code that "confuses" compilers (or it's simply broken). I failed to reproduce the issue on x86, and cross debugging somehow still don't work for me, so I can't tell more.
