Lots of information for embedded dev's coming from other Operating Systems! If that's you then the authors suggest having Running Linux (http://oreilly.com/catalog/9780596007607/index.html) and Linux kernel in a nutshell (http://oreilly.com/catalog/9780596100797/index.html) available while you work with this book.

Definately a good read! Minor issues are the slight wordiness in places and the lack of proof-reading here and there. Embedded systems skills are gaining popularity and you can get some hands on working with a minimal system and trying out the stuff in this book.
