Re: Bug#711135: Re: compiling a bootable kernel for ia64 (itanium2, mckinley, rx2620)

[Gatis Visnevskis <gasha@pie-dabas.net>]

Hi all

I got working 3.2.0 kernel after some work. Without recompilation.
HP rx4640. That was 2 years ago. Server switched off for cost saving :(

Started to install toolchain for compilation, but not finished.
Internal disks were too small, some 36 gb i think.

It seems that i have to boot my server, and try again, as there is some
light in end of tunnel. I was hoping to get LXC working on ia64 some
day.
