	Hello,

	I have built a 2.6.22-rc7 on sparc32/smp to debug kernel. The only 
error I see is "BUG spinlock recursion" with call trace. How debug this 
mistake ? How can I find information about spinlock debugging ?

	I have tried to boot with the same kernel and maxcpu=1 option but this 
box ever boots with two CPU's online. How can I force this kernel to 
boot with only one CPU ? Does MAXCPU variable only work on i386 ?

	Regards,

	JKB
