Second issue: amd cpu based desktop locking up at random with no error messages. The only symptom is there are a lot of [900.000017] [Hardware Error]: No human readable MCE decoding support on this cpu type errors in syslog and the numerical number is different each time. I used the nomce option which does stop the error messages, but the amd cpu based desktop is still unstable, with random lock ups. MCE = Machine Check Error. Read: your CPU is probably failing.
hmm perhaps but runs just fine on 11.3 or any other os, I've used on this box prior to 11.4 update, so thinking that's not it. This happens only with 11.4, so far.
Thanks
MCE's can be tricky things to troubleshoot. 'Generally' (overwhelming majority of the time) a MCE is hardware, a hardware/firmware message that is logged by software. However "something has to throw the exception". I ran into a really strange problem with the nvidia driver on openSuSE causing (or at least involved in) an MCE: http://lists.opensuse.org/opensuse/2008-04/msg00392.html I still run the same nvidia card, so I never found out what the actual issue was. It was on a Tyan Tomcat 8KE board with and Opeteron 180 proc running x86_64. Best thing you can do is try swapping hardware and seeing if the mce goes away. As far as 11.4 goes, I'm running it on x86_64 and I have been very, very pleased with the 11.4 release. It is by far one of the best since 11.0. I don't know 11.3, but the default kernel with 11.3 sucked for me. I still have 11.3 running on a box with a 2.6.35 kernel and I have no complaint. As for 11.4 with the 2.6.37 kernel -- it has been rock solid on a very finicky Toshiba laptop with Atheros wireless and ATI graphics. (I did have an Xorg issue that is currently being fixed: https://bugzilla.novell.com/show_bug.cgi?id=678264) Whatever the issue, it looks like your box is tripping on something that may be one of the features that has been moved into the kernel since 2.6.34 (11.3 default) There have been a *lot* of changes between 2.6.34 and 2.6.37. It may just be one of those issue "where all the stars line up on your box" and you have hit a bug in the code somewhere. Because, honestly, all things considered, 11.4 has been the best release openSuSE has had in some time. (no flames, just my humble learned opinion :) -- David C.
