I've spent months hunting for this random crash bug until today when I
finally found a way to reliably reproduce it (run a software that I
develop under valgrind). Log received over netconsole:
http://pastie.org/5848168
Is this a known issue or do you need more information to debug it?

Hmm, this happens while running memcheck-<something>.
A couple of things:
* can you try the same way of reproduction without the proprietary
nvidia module loaded?
* can you try latest kernel, 3.8-rc4 or 3.7-stable?
* let's also add linux-usb to CC.
HTH.
