There is > nothing in that code path that should remove the power. With reboot=c, reboot=w and reboot=h it still powers off. With reboot=b it actually reboots. With 2.6.13-rc2 (the previous good kernel here) it just works and does a reboot with no special parameters. I also have lapic nmi_watchdog=1 in boot command line but removing these does not help either. So far I only know that rc6+somegit and rc7 power off and rc2 works, will try som kernels inbetween. -- Meelis Roos (mroos@linux.ee)
