i've saved the merged 2.6.26-rc8-tip-00241-gc6c8cb2-dirty tree into tip/tmp.x86.xen-64bit.Sun_Jun_29_10 and pushed it out, so you can test that exact version.
Looks like the setup.c unification missed the early_ioremap init from the early_ioremap unification. Unconditionally call early_ioremap_init().
applied to tip/x86/unify-setup - thanks Jeremy.

I've reactived the x86/xen-64bit branch and i'm testing it currently.

config and full log can be found at:


This config doesn't have CONFIG_DEBUG_KERNEL enabled, let alone CONFIG_CPA_DEBUG. I've noticed this seems to happen quite a lot: there's a disconnect between the log file and the config which is supposed to have built the kernel. Is there a bug in your test infrastructure?
