Just reproduced this on the 13.12 release image...

- I created a clean 13.12 LSK Android image and copied script for comment #44 to the 'sdcard' partition.
- I booted image from USB on TC2 and waited a minute or so for most CPU activity to stop.
- Ran disablesuspend.sh so that the Linaro animated wallpaper woul run continuously.
- Connected to vexpress from my PC using ADB.
- Ran 'adb shell /sdcard/hotplug.sh'
- After realising I wasn't logging output from that command I stopped it with Ctrl-C
- Ran 'adb shell /sdcard/hotplug.sh >~/hotplug.log'
- Shortly after the kernel carashed with a NULL pointer exception in timer_softirq (see attached log)
