Comment 13 for bug 653134

I can confirm this as well on 64bit... installed 10.04.1 64bit to an Athlon II system via wubi, then upgraded to Maverick. I do not get the soft reboots that jibel is seeing, but I am seeing the same messages noted in the original description, and then a system lockup. I have a feeling that my system not rebooting is more just an effect of how the hardware is handing the hang.

In any case, with the exception of the system resetting itself (which in my experience is not that unusual), I'm seeing the same problem here.
