Thanks Tony, I rebooted and put "nomce" in the boot options and these hardware errors stop (the other errors were related to a CD in the drive, see other post). Great tip. Not at all sure what this does though. I wonder if this is analogous to disconnecting my oil pressure gauge in my car? In any case I'll read up more on MCE and most likely make a permanent entry to my grub. Also not sure why this error occurs in 11.4, as it didn't on 11.2 and 11.3, exact same hardware. I'd agree this seems like its a kernel thing and not an openSuse thing.

I installed openSuse 11.4 yesterday, and am getting system error messages (/var/log/messages) as follows. The 4 Hardware Error messages are repeating every few minutes. I have no idea what this means. Can anyone clarifiy?

FYG I did a clean install to a dir that previously ran 11.2 and later 11.3. These errors were not noticed on those installs. No hardware changes have been made, except I have a USB HD plugged in to transfer my older docs and stuff. 32 bit on AMD Athlon.
I also have an amd athlon cpu, upgrade to 11.4 from 11.3 started getting a lot of "No human readable MCE decoding support on this CPU type", stuff I found on the web said to try using the nomce option at boot, I could find nothing that indicates what this does / does not do, at least not in laymen terms anyhow. Seems this No human ... error is an issue with amd cpu's with version kernel that ships with 11.4, that's based on what I found.
Suse 11.4 on my amd athlon desktop is a 100% disaster, the system is a total mess. As I type this I am reinstalling 11.3.
In the digging I did on the internet, several posts I read said the mce error message seems to be an issue with 2.6.37 kernel and I think I found a post some where, saying this might be fixed or something was changed on mce in kernel 3.6.38, so I figured I try updating kernel. I found a 3.6.38-rc7-19 kernel here http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_11.4, installed it. I'm assuming it's release candidate 7, and not sure what effects might be from using this kernel. But I have a usable system for now.
One more thing the mce error kept showing up with the desktop kernel, I'm using the default kernel, and all seems good for now.
