My RasPi arrived and I gave it a try with the Debian 6 distribution suggested in the downloads page on raspberrypi.org. Observations: I ordered mine from RS components together with a power supply. The RasPi boots from SD (a slower 16GB Micro-SD card) within some 20 seconds (to the Linux single user login prompt). Switching to run-level 5 takes some 45 seconds (the X server starts within a few seconds, but there must be quite a lot of activity going ... Logging in on GDM takes only a few seconds (maybe 10) to get an Openbox LXDE desktop up and taking commands. The X11 server uses the uncommon geometry of 1824x1104 on my 1920x1200 screen (connected via HDMI). Now for the "bad" parts: As soon as I connect a wireless mouse dongle (whether M$ or Logitech does not matter), messages about USB device resets are logged every other second (for the USB device number corresponding to the mouse adapter). I also had lots of error messages: smsc95xx 1-1.1:1.0: eth0: Failed to read register index 0x00000114 smsc95xx 1-1.1:1.0: eth0: Failed to write register index 0x00000114 but cannot reproduce this message today. A Google search gives many hits, these problems do not appear to be uncommon. I've read the opinion, that the USB problems are caused by instable 5V power, but given the rating of my power supply, this should not be the case. Another common problem seems to be caused by active USB hubs that feed current into the Raspberry PI's USB port. This seems to affect my configuration too: As soon as I connect an active hub, Ethernet traffic stops (the Ethernet chip is internally connected to an USB hub). The Linux drivers are not yet finished, e.g. the sound driver always stops playing after a few seconds. All in all it still is an impressive little device and I hope to find some time to study its internals over the next few weeks. Has any progress been made with regard to leveraging the existing Linux boot support for FreeBSD? Regards, STefan
