2.6.14-mm1 doesnt bootup on PPC64

[Srivatsa Vaddagiri]

Hello,
	I am having problems with booting 2.6.14-mm1 on a PPC64 box 
(p630 - 4way Power4 box). I get this message :

"<3>Badness in smp_call_function at arch/powerpc/kernel/smp.c:202"

System locks up after that (doesnt respond to Softreset also).

The message corresponds to the WARN_ON(irqs_disabled()) check in 
smp_call_function. Surprisingly I dont get any backtrace after this message. 
I configured so that xmon is enabled by default hoping to breakin via
Softreset, but Softreset failed to breakin too. I in fact tried extracting the 
caller of smp_call_function via the built_in_return_address(0), but that also
didnt give me anything.

So is this a known issue and a patch exists to fix it?!
