    Any ideas.

    Google says you'd need to check your system to check for problems, for example, by running memtest or by using other distros/OSes.
    The first thing I always do when I find problems is to google them and check for similar things. If there aren't any, the problem is probably in my side... in this case: http://www.google.com/search?q=%22un...22&btnG=Search I can't find similar patterns. Anyway, you didn't provide any contexts on when and how it crashes, so I don't have enough info to say anything.
    If you are able to reproduce and you are confident that the problem is not in your system, you report it in https://bugzilla.kernel.org/ .

      This is getting stupid.

        It's clearly not radeon when vbox is causing it too. Your system is hosed. Run memtest.

          Did it on various occasions. No errors.

            How long? One pass is not nearly enough, I've seen systems where the errors only showed up on the fifth pass.

              I've seen systems where memtests would not find anything at all while running with faulty RAM. However, decompressing huge ZIP files would eventually give CRC errors even if ZIP file is okay (key thing is to keep ZIP decompressing data for about 10 minutes or so). It looks like if ZIP memory access pattern is more localized and can increase themperature of particular IC/module higher than memtest patterns would normally do. So it can be very strange case where memtests does not detects any trouble, but some rare localized system loads still can cause memory corruption. Such cases are really hard to pinpoint. And btw, bugged driver or some wrong hardware actions (e.g. bad DMA transaction) can also corrupt system memory in really strange ways.

              P.S. on side note, ECC RAM is a really good thing in this regard. Special thanks are going to AMD, who makes it possible on desktop hardware at sane price tags. This way I can be more or less *sure* RAM works reliably.

                3 passes no errors.

                3.12 kernel and maybe early 3.13 were much more stable. Not that it happens frequently.

                    I'm with the others on this probably being memory going bad, compiling large code bases are actually another good test, basically if GCC sigsevs you know you've got memory issues.

                      Does it happen without virtualbox loaded?

                        Yes. The thing is that there is nothing that can reproduce it. It just happens.
