Re: [Xen-devel] Xeno-unstable crashing at boot

OK, I did that and planted a few dump_stack() calls in the acpi code:

I've just checked in a fix -- the Xen-specific acpi_map_table() function was both unnecessary and broken. Hopefully latest unstable will boot on your test machine.

Just updated and rebuilt - still crashing.

It's probably crashing in a different place now. Can you please send output from latest build, with early printk and some suitable dump_stack() calls inserted?

Here's the crash from a build at 4 p.m. yesterday.
Unfortunately it seems to have hosed my machine completely,
and since I'm remote at the moment I can't reset it.
