I should note before I start that I did open my chumby to solder wires to the debug serial port. However, after this procedure it was working fine for several days and the debug port was working (I used "screen" as my terminal emulator over 38400 baud).

Last night, after leaving the chumby up and running alone for several hours, I came back to a solid white screen. Rebooting gives me nothing but this solid white screen. If I leave it alone for a few minutes, it changes to a white screen with a solid black line down the middle - and during this process the debug port spits out a bunch of stuff. Probably part of the boot process.

Now here's the bummer: The debug port, which was working just fine, now spits out a bunch of gobbledygook! I can see that some of the characters are bits of valid words that do come up during the boot process (like part of the word "Chumby") so I'm wondering if the port is running at some other baud rate now?? 38400 is not working. I've tried a few others, but no luck, just garbage.

I've tried loading a USB thumbdrive with various scripts, including attempting to automatically start sshd as an alternative to get in, but no avail. Ideas?

A bit annoyed because I've only had the thing 2 weeks and it may already be bricked ...

Thanks!
