Can you run lspci -v and lsusb?  I'm wondering if the USB 2.0 ports are
part of an EHCI host controller or an xHCI host controller.

Can you run netconsole to capture more of the messages before that?  If
you need help with setting up netconsole, see:

Would this happen to be on a Lenovo W510 laptop?  I've received reports
of different oopses caused by disconnects, while running 2.6.35.8:

Do you see panics or oopses when you run 2.6.35.8?  Or did you just
upgrade straight from 2.6.35.7 to 2.6.36.2?
