If that machine covers most of the bases ... then it should be
good enough.  Did you set CONFIG_PRINTK_TIME=y?  I belatedly
looked back at the full console log for the system with this
patch in place and timestamps turned on ... and noticed that
the first few timestamps are garbage:

Better than crashing ... but not as nice as it could be.
