Where did the problems start, rt4? (i.e. rt3 > works fine?) ok, fixed a couple of bugs on x64, it boots on my box now. The main breakage was the elimination of the preemption-disabling soft irq flag in -53-05, that unearthed an irq-flags 32-bitness bug in the spinlock macros, which was there for ages. This resulted in the early reboot during bootup. I've uploaded 2.6.13-rt12 with the fixes.
