With the latest version I didn't have boot problems on x86_64, but I haven't tried on other architectures. I run cyclictest with some load background and got a maximum latency of 125us (only run it for 10 minutes).

Thanks for the feedback. After some more debugging, it looks like the 
boot problem is cased by kexec on the test machine. IOW, the test kernel 
seems just fine.

Thanks,
Daniel
