I think we finally found the reason and a fix for the "CPU:1 is stuck" problem :-)
See the patch I've just sent to the mailing list:
[PATCH] parisc: Do not crash 64bit SMP kernels on machines with >= 4GB RAM
https://patchwork.kernel.org/patch/3099061/
It would be nice if those people who had problems could verify if this fixes it.
At least on the J6750 from Dave Land I was now able to successfully boot the 64bit SMP kernel.
I think this should even fix the SuperDome SMP problem - if someone can test?
If you might be too lazy to build yourself a kernel, just try my 3.10.17-based installer image:
http://ftp.parisc-linux.org/debian-ports/unstable-boot-image/lifimage
To select the 64bit kernel at boot, choose in IPL "0/vmlinux64" as kernel image.
Usually palo would otherwise choose the 32bit kernel...
In case you want to run a full installation, the instructions are available at
http://wiki.parisc-linux.org/Debian_Ports_Installation
