https://bugzilla.novell.com/show_bug.cgi?id=759820 https://bugzilla.novell.com/show_bug.cgi?id=759820#c0 Summary: Hardware Error and freezes if power save mode C6 activated Classification: openSUSE Product: openSUSE 12.2 Version: Factory Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: ath@muffti.de QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0 Two weeks ago I bought a new board, Proz and RAM. ASUS Crosshair Formula V, BIOS 1301 (current) AMD FX-8150 32GB DDR3-1333 RAM Before there the system run with the following components: OSS11.4 MSI K8N2 Diamond FX940 8GB DDR2 RAM After the upgrade I had sporadic system freezes (only Reset helped, no kernel panic!). In the messages.log I found some errors: Apr 15 15:12:16 achim-linux kernel: [ 3900.695217] [Hardware Error]: No human readable MCE decoding support on this CPU type. Apr 15 15:12:16 achim-linux kernel: [ 3900.695232] [Hardware Error]: Run the message through 'mcelog --ascii' to decode.

Apr 28 17:44:53 achim-linux kernel: [ 300.705150] [Hardware Error]: cache level: L2, tx: DATA, mem-tx: DRD Mostly CPU2 was affected, sometimes CPU3 I have limited the problem so far as possible. If the Vanilla-Kernel was running only error messages (sporadic) come without a system freezes. If the Desktop-Kernel was running, it comes error messages (often) + system freezes. Furthermore the problem occurs only if the power save mode C6 was activated in the BIOS. If I activate only C1E then there comes no errors.

I would search for BIOS update first. If the problem persists, please make sure mcelog package is installed and the mcelog daemon is running. Please attach /proc/cpuinfo, /var/log/mcelog (filled with some MCEs I expect) and dmesg output. Are there any edac drivers loaded on this CPU (lsmod |grep -i edac)? If yes, please try without them (/etc/modprobe.d/99-local.conf): blacklist edac_module1 You possibly have to blacklist more than one module/driver. Double check whether there are dependencies by making sure no edac driver is loaded: lsmod |grep -i edac -- 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.

It would be great if you can post the output of one processor of: cat /proc/cpuinfo I would like to forward this info together with: they might have an idea which CPU setting (wrongly initialized by BIOS) could be wrong. I am setting the bug to invalid as we (from OS perspective) cannot do much about this, beside blacklisting bad HW/BIOSes. -- 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.
