Hey,

I installed Xen 3.4 enabling Power management options -> ACPI -> Sleep states. But whenever I try to hibernate ( echo "disk" > /sys/power/state ) in dom0, the system halts and I get the messages like following:

***********************************************************************
RDX: 00000000000 RSI: fffffffff805520c0 RDI: 00000000000000
......

****************************************************************

Then the system gets stuck here and I need to turn off the power to boot the system again. According to the roadmap of Xen 3.4, the feature of hibernating seems to be supported. I am wondering if I have missed something or hibernating is not supported in Xen 3.4 yet.

Any comments are appreciated. Thanks.
