That looks to me (after finding out how to build that testsuite: make
check!) like it is related to latest changes on pthread_cond_xxx. Gilles
is on CC now.

If you happen to have time, I would suggest narrowing the cause down by
switching synchronous printk on (ipipe_set_printk_sync(&rthal_root);
ipipe_set_printk_sync(rthal_root_domain);) and then spreading some
printk to the init routines of the nucleus, trying the find the
problematic line(s). This printk will even works under hard IRQ lock, so
also endless loops in the timer handler can be detected that way. It's
just a bit time-consuming for the operator...

Is there already some doc somewhere? Maybe I was just blind.

Well, I would offer to spend a few cycles of our development server, but
our build environment and target boards are already the most common
ones: latest compiler on x86 for x86. Boring, I know...

Then please check for the CAN drivers (same as with RTnet: some only
build for PPC) and the latest switches of the POSIX skin.

Ok, and if we do not respond, just yell loader! ;)
