Topic: Replacing your own kernel is not recommended yet
Warning, don't follow the instructions on the wiki page http://wiki.chumby.com/mediawiki/index. … for_chumby on how to change/update your kernel version, they don't quite work properly, and you might end up with a chumby that is only in "special options" mode.
For some reason I don't think that the kernel source provided as a download is the one that is running in the latest versions of the chumby, based on the configuration and drivers listed, and hopefully someone will fix this soon...
