Bug Description
If the Streamline tool in DS-5 [1] is connected to Snowball then the board will lock up, requiring a reboot. This only seems to occur if the screen is static (unchanging), it works OK if the animated wallpaper is running, or you keep wiggling the mouse, or whilst running 0xbench 2D and 3D tests.
I believe this bug is due to the recent Mali driver patches which added support for Streamline and came with the known issue:
"Attempting to read L2 cache counters when the hardware block is powered down could potentially lead to a hang due to a lack of locking. This will be addressed in a future driver update."
So it seems reasonable to surmise the lock-ups may be due to this.

The lock-up occurs when starting or stopping Streamline data capture.
As it does not occur if the L2 cache counters are not accessed, this issue can be worked around with the attached patch to the Mali drivers.
