All 3 systems have problems when rebooting or powering off with openSuse 12.2. The typical behavior I am seeing is a hang at the POST. If you reboot the system, it will hang with a blank screen at the POST. If you power the system off, when you power it back on it will either hang at the POST, or hang under Linux during the boot before you can type anything. If you perform a regular power off, then unplug the AC power, then plug it back in and turn it back on it works fine. Once it has hung at the POST, or under Linux during the boot, holding in the power button to turn it back off, and then turning it back on works fine. The Quanta system generates an entry in the IPMI log every time this happens saying "IERR Asserted". Based on some reading I've done this indicates an internal error in the CPU. Is openSuse 12.2 somehow leaving flags set incorrectly on the CPU for shutdown? CentOS 6.3 and Gentoo w/ a 3.5.3 kernel both work fine on this hardware. Reproducible: Always Steps to Reproduce: 1. reboot a quad socket Romley system, or power it off and then back on 2. It will hang at the POST 3. Actual Results: System hangs at the POST, or sometimes hangs early on in the Linux boot process. Most of the time it's a POST hang. Expected Results: Correct powering off / on / rebooting. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
