Maybe this has nothing to do with the binary data that is output. Do you call "printk" from interrupt context? If so, there is currently a known bug (but no fix yet) about characters getting jumbled when using printk in interrupt context. Look at that thread of discussion: http://lists.linuxppc.org/linuxppc-embedded/200303/threads3.html#00109 The subject is: Problem of concurrency in arch/ppc/8260_io/uart.c As a work around, I would suggest to defer your traces to a kernel task (with schedule_task)... or to fix the bug! ;-) ...whichever is more appropriate.
