Problems with SMP

	Hi, All.

	Now, that I could get a 2.4 kernel compiled for my quite old
	PowerMac 9500/180MP, I would like to get SMP working. This
	machine is quite slow for a lot of tasks, including rendering
	web pages. So, getting the second CPU working would actually
	be a great boost of speed.

	I have compiled a SMP kernel, but these are the messages that
	I receive when the kernel is booting:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
PowerMac motherboard: PowerMac 9500/9600
Entering SMP Mode...
Processor 1 is stuck.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

	After this, /proc/cpuinfo only shows information about the
	first CPU.

	So, is this a known bug? Would the cause of this problem be
	that I am booting with BootX? Should I send more information
	to linux-kernel? Which information would be necessary?

	I think that I'm falling in love with the PowerPC architecture
	and if I get a bit more of speed, I'd love to help compiling
	packages from the Debian repository or to help with anything
	that I can to make Debian better.

	Thanks in advance for any information, Roger...

P.S.: I'm attaching the complete dmesg output to give context to the
excerpts above.
