I have a brand new Pi (Rev 2, Mod B) board with PiFace addon connected. Power supply is 5V/1A.
- Pi completely locks up after some time (overnight).
- SSH session gets disconnected (connection reset)
- Pi doesn't respond to pings anymore
- PWR led remains on (red)
- LNK, FDX and 100 Leds remain active (LNK occasionally blinking)
- HDMI output still has signal, but screen all black
- Keyboard nonresponsive
