High CPU temp, suspend problem - xen 4.1.5-pre, linux 3.7.x
Hi,
I''ve still have problems with ACPI(?) on Xen. After some system startup or
resume CPU temperature goes high although all domUs (and dom0) are idle. On
"good" system startup it is about 50-55C, on "bad" - above 67C (most time
above 70C). I''ve noticed difference in C-states repored by Xen (attached
files). On "bad" startups in addition suspend

[RFC PATCH 00/35] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
