On a Digital Personal Workstation 600au (Miata, as is silkscreened on the motherboard), the stable kernel (2.6.26-gentoo-r2) works perfectly (to the entent I've tried it out, of course) when configured with CONFIG_ALPHA_GENERIC (selected in "Alpha System Type", option #1), but does not boot with CONFIG_ALPHA_MIATA. It seems that something IDE related is the culprit - I get strange error messages with the IDE cable plugged it, and without it plugged in, it boots to login (but doesn't let my input anything, and serial console doesn't get a login).

I made two identical .config files except for this option - one boots, the other doesn't. What are the kernel differences between kernels built with these two options?
What kernel sources did you use? Also, gather all relevant information right here and don't refer to (lengthy, changeable) forums threads.

I believe that this is all the relevant information that I have - I'll post the .config files, but it shouldn't matter too much (since I've narrowed down the culprit).... I'm also going to try vanilla-sources just for fun.

I've done a minimal install on my Miata and built a kernel with your (failing) config. The bug happens here, too. Unfortunately, I can't use this machine to actually hunt down the bug. I'll CC kernel@g.o, see what they think.
As this is a kernel and not a gentoo-specific bug, I recommend opening a bug in the kernel bugtracker (http://bugzilla.kernel.org/) and/or writing to lkml.
