dac922, First off, my Ubuntu 12.0.4 LTS Server was just upgraded to Kernel vmlinuz-3.2.0-53-generic-pae. But I see in your post that you're working on kernel 3.8.0-31.46. Am I supposed to upgrade 12.0.4, running in production to kernel 3.8? Yikes!
In the last paragraph of your comment, you mention seeing the buffer I/O error messages. Shouldn't this mean that bug #1217189 should be re- opened to address that issue? (It's currently got a comment that "it's a duplicate of #1215513"). I still think /etc/init/zram-config.conf should be looked at, for a possible calculation error. (As mentioned in an earlier post by me, this file exists, if you "apt-get install zram-config" as root (or with sudo). To repeat my question, was that configuration file looked at, when you were doing the kernel patch?) Thank you and best regards, Kenneth Parker, Seattle, WA P.S. I'm a Computer Consultant, specializing in Network and Security issues. I could be working on problems like this, except that, as a "general troubleshooter", I'm typically up to my eyeballs in alligators, and prefer to deal in the "big picture", unless there's a good reason for getting into "detailed troubleshooting mode", like having error messages when booting my server.

First one was while running Virtualbox (windows guest) but later have been without virtualbox running for example while shutting down or while reading a webpage. I could not find any relevant log, but I'd post any log file considered useful. This has hapened in 2 different machines (the one im reporting from is intel with intel graphics and the other is AMD with radeon graphics). Both 64 bits. Up until 3.8.0-27 inclusive I had not had a lockup in years in any of those machines. I have been running Ubuntu 64 bit since at least 2008 in one of them.
