A bug where the serial console could get stuck on SMP IFF a kernel and a
non kernel message were output at the same time did get fixed
(yesterday) other than that I'm not aware of any problems in this area
but the maintainer may have more ideas.
Diff is tiny if you want to see if that is what you hit, although it
would be remarkable co-incidence and luck if it was ;)

Never seen CR, nul reported. Would the blades happen to use rlogin to
manage this remote serial do you know ?

Its hard to maintain an old release and just merge all the fixes into it
backporting when neccessary. At the kernel summit before 2.6 this was
discussed a lot. There are a small number of groups of people who wanted
this for the long term. Said groups either maintain such trees and sell
support/services for money, or rebuild the output of the former as a
community project.
It therefore seemed reasonable that those who want it should bear the
cost, or figure out how to maintain such backports between themselves.

The GPL is very careful about this. If you ship the sources to your
customers then you have done your duty. If your customers choose to give
it to others so be it. If the others ask you for changes then I believe
the phrase is "business opportunity".

Embedded can be more problematic because it is harder to spread the
load, but there are communities of people who looked at things like Red
Hat Enterprise Linux and decided that they could use the code but didn't
currently need/want the training, support and services that are what
really makes it. One obvious example is Centos which is a community tree
derived from the RHEL work, rebuilt, rebranded without
support/services/etc and downloadable for free.
