Look at this last line. The "<7>" is a priority marker. Normally it
marks the start of a line, and should be hidden. So you seem to be
missing a line break just after "20050309)"...

I guess you have a multicore processor (or some other sort of SMP), right?

I think kernel messages are not completely synchronized by design, for
reliability reasons. (e.g. to make sure critical error messages /
backtraces can get through on a dying system).
