Fresh from the box, I plugged in an HDMI cable, an Ethernet cable, a PC World essentials USB keyboard and USB mouse, and a 4Gb Samsung SDHC Card with the debian 6 image. I added a power supply (5V 1A yoinked from my HTC phone) powered up and got pretty lights on the board and a kernel panic on my TV.
Ouchy. Consulted the troubleshooting page and unplugged everything except the HDMI and reconnected the power. Got as far as the login. Reattached the keyboard: kernel panic.
Is my keyboard just too cheap?
