Just thought I'd note that among other issues that I am having (see ypbind 
hanging thread), since updating to current as of a day and a half ago, I 
can't boot into a xen dom0 without a USB keyboard plugged in (this probably 
extends to other USB devices) OR I require acpi=off as a boot parameter.

Before the update, all worked fine. It seems to be a combination of acpi and 
usb. Unfortunately I can't readily test.

I am also noticing long delays on domu boot.
