I upgraded to the latest kernel for 11.4, from within Yast, and after rebooting I get these MCE kernel errors.
Apr 26 16:29:40 fmt-itops kernel: [81228.339471] [Hardware Error]: No human readable MCE decoding support on this CPU type. Apr 26 16:29:40 fmt-itops kernel: [81228.339479] [Hardware Error]: Run the message through 'mcelog --ascii' to decode. <snip>
The kernel running is;
2.6.37.6-0.11-desktop #1 SMP PREEMPT 2011-12-19 23:39:38 +0100 x86_64 x86_64 x86_64 GNU/Linux
...and the CPU type; CPU model name = Intel(R) Xeon(R) CPU - X5650 @ 2.67GHz
What can I do to prevent these errors?
Many thanks,
James
I encountered this a few years ago after an upgrade. My memory is very fuzzy, so don't hold me to this: If you are just getting the errors for the first time, it might be the kernel. IIRC the kernel code has some explicit handling for certain boards known to be problematic with MCE, and there may have been some other peculiarities with this code. While IIRC the mcelog package can be removed, I think there may also be a kernel argument that disables checking ("nomce"). I'm not suggesting you just dismiss the error msgs; they could be valid so are worth following up on. What I did though was install a newer kernel and the errors immediately ceased. Since then they haven't reappeared with all the subsequent kernel upgrades. -- Thank you for the illuminating reply. Much appreciated. I should have made it clearer that he errors did not occur until immediately after the kernel upgrade. The kernel running, 2.6.37.6-0.11-desktop, is the most recent provided by Yast in opesuse 11.4. When I run mcelog I get; #mcelog --ascii < /var/log/mcelog mcelog: failed to prefill DIMM database from DMI data mcelog: failed to prefill DIMM database from DMI data mcelog: failed to prefill DIMM database from DMI data mcelog: failed to prefill DIMM database from DMI data <snip> I get the same if I cat the file. Not sure what to do next. Any suggestions? Thanks again, James -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
