Thanks Konrad. I've tried your patches, and whilst I have not seen this 
crash in cpuidle_register anymore, the others are still present (in 
build_schedule_domains for example).
I've stumbled on a bit of interesting info - using dom0_vcpus_pin on xen 
commandline stops both the xen scheduler and dom0 kernel crashing and 
all works fine - made dozens of succesfull s3 attempts. Was wondering if 
you guys had any thoughts on this? Is the dom0 kernel even supposed to 
cope during s3 in non dom0 vcpu pin case?
