Hey,
I'm trying to set up linux on a certain ARM device and I've currently just compiled the kernel. I setup uboot and booted from a SD-card successfully. Now I attached a usb-to-serial adapter to the board and was watching the kernel boot logs. Here's a snippet:

Why are there all these duplicate lines in the log? Seems like something prints out a message before the main kernel log does. I've setup the kernel to print out timing information, so the lines starting with tags like "[ 3.481046]" are the correct ones. The other ones seem to always start with a tag like <3>, <4>, <5>, <30>, etc.
Is there some kernel parameter I need to disable at compile time to prevent these entries from appearing?
Thanks!
