We happened to see it when we rebased to the 3.6 kernel, but as far as I
can see, the bug has been there as long as print_time(), which comes from
084681d14e42 ("printk: flush continuation lines immediately to console")
in 3.5-rc5.  When I was doing a web search for info on the problem, I found
at least the following reports:

https://bbs.archlinux.org/viewtopic.php?id=148100
https://lkml.org/lkml/2012/10/17/81

so yeah this seems to be stable material.
