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 Helge -- To unsubscribe from this list: send the line "unsubscribe linux-parisc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
