For whatever reason CONFIG_DEBUG_TIMEKEEPING was flipped on in the newer versions, no idea why and how I did that. However, that "may have a (very small) performance impact" in the Kconfig isn't exactly true. When output through my 9600 serial line it slows the kernel down to a crawl, so much that it doesn't even boot. So, everything is fine for now. Regards, Eike
