I think, there is a device connected to the connector on the motherboard, to which the reset button would normally be attached. > As for the problem itself, do you have C states enabled in the BIOS? > This sounds similar to several errata published for the i7 series. I'm not sure how to tell whether C states are disabled/enabled. What would those BIOS options typically be called? Also, should I enable or disable them, in order to workaround those errata that you mention? Should those errors have occurred with xen 3.x as well, if those were a result of the errata you mention?
