Yes, disabling acpi makes it boot.

Unpatching bk-acpi it _sometimes_ hangs during boot.

It seems that hotplug "subsystem" is having problems (I use debian/sid), 
because it stucks during

/sbin/modprobe -s -q ehci_hcd

Note that I'm seeing this after a /etc/init.d/hotplug start (after a 
successfull boot), but just before I had a kernel oops (see attached 
file) when issuing a /etc/init.d/hotplug stop.

Hope it's helpful someway.
