Description Peter Teoh 2012-05-12 06:07:37 UTC 
The laptop crashed whenever the USB devices are not gracefully unmounted:

(or perhaps crashed due to some other unknown reasons).

Configuration:   3.2.11 kernel on Ubuntu 10.04 LTS 64-bit version.   LENOVO V570 laptop (i4-2450M).
Comment 1 Peter Teoh 2012-05-13 06:43:38 UTC 
Looked at the photostream:

it is a collection of the numerous crashes (7 on the same machine/OS version across a period.

The crashed point happened at different position in the kernel, but is usually associated with pulling out the USB devices without gracefully un-mounting it in the first place.
