Right now I do not think there is much choice to fix this (other than not touch /dev/hpet on AWS). The linux kernel deliberately wants to set a level triggered interrupt. The xen hypervisor has no support for that (there might be some addition done but certainly not in any released version of Xen). And as "error handling" forcefully crashes the domain.
