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
