I've been working on getting the RaQ2 to work with the current 2.6.14 kernel, but no luck at all. The last success I had was with 2.6.12.x series.

I'm looking for ideas, patches or whatever to get this working again. I know it has to do with the kernel using 32bit addressing instead of 64 bit, but have no clue where to start.

Here is what I get when I attempt to boot it.

Thanx for all your assistance.

Hmm, I'm unable to boot a 64bit kernel on either IP27 or IP30 here. Appears to die very early in the kernel code. It looks like your kernel also dies before doing anything meaningful, so I wonder if this is some common thing.
