My brain also crashed while trying to figure out your problem... a. crash output is the outcome...but what are the inputs? the background OS is in the bootup message, but did u wrote your own serial drivers? what did u do in the serial drivers? b, more info on the background OS.....in particular, where (URL) and what are the steps u followed install the software on the hardware? c. crash may be arch specific or indep, so some hardware info please. sorry i may asking a lot of irrelevant question here...but u have to decide how much to provide as "relevant"....based on your intuitive guess on what went wrong....thanks.
