Hi,

We have a single-core Pentium M industrial PC equiped with Xenomai
2.5.2 patched vanilla Linux 2.6.32.7.
We have two builds of the kernel: one that causes a reliable system
reset when starting a 'heavy' Orocos application (lot of thread
creation/deletions), the other is rock solid. We think it is related
to thread creation in the native skin, since we could at least twice
cause the reset by just creating a native thread (that was meant to
block on a semaphore) but this was hard to reproduce. Stack size was
set to 128k, but only trivial code was executed.We had the impression
that enlarging the stack size to 256k caused less resets, but it was
still very frequent. Setting the stack size too low caused segfaults
in the app, not a kernel crash.

The stable config and the diffs between both configs are in
attachment. Read it as: apply this patch to make it unstable. Any
clues what is the most likely suspect ? Could the xenomai watchdog
cause the reset ?

Thanks for any pointers, we're prepared to bisect this, if any one
knows a tool to do a bisect on a set of config options, we'll be glad
to use it.

Cheers,
Peter
