FYI: The current assumption is that there is a hardware issue here resulting in corrupted memory. We are seeing some odd things in the hardware logs (but Linux apparently is /not/ detecting anything - no bad pages reported, for example). We tried a firmware update for the platform, but that did not fix things.
My next steps are to see what kind of platform diagnostics are available, and I'm also trying to acquire another system to try the tests on (to see if they reproduce or not).
