Hi list, 

I tried to setup XEN 4.0.1 (Debian unstable packages compiled for lenny) on 
my workstation, but run into trouble. XEN 3.4.3 works flawlessly on the same 
hardware. Booting with the noapic parameter solves the problem. 
Feel free to ask for additional information as needed.

Could you try below patch (with "acpi_skip_timer_override"
removed again)?
