Ubuntu, 11.04 (fully updated)

Forums: 

My main PC seem to have caught galloping bit-rot.
It's been working perfectly for two months but, in the last week or so it's started spontaneously hanging. I was just filing some emails in gmail (via Chrome browser - v13.0.782.218) and the whole system just hung; not even mouse movement. I haven't added any hardware recently. the hardware is only a couple of months old and I'm not running anything particularly weird except (maybe) VirtualBox (non OSE version).

There's nothing I can see in the logs (kern.log and syslog - excerpts below) and I can't find anything on the Ubuntu bug list which might affect me.

Any ideas about where I can look trace-wise and/or if some of the latest updates have caused any grief? :(
