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.

I tried to give it a look 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.

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.
