PAE MFC brought an incredible instability to stable branch.  It

Right, say if still the OpenSSH did or still comes out to be real. Ops, now thats
right, we don't have 3.6.1 in STABLE, why ? It was released on April 1, does
that not give one enough time to merge this in ? Perhaps someone new is needed
then to manage the import of OpenSSH if that is the case, if it is re@ or other
decision member's of FreeBSD wouldn't allow it, then perhaps its time to restructure
that part.... I'm not sure what the case is as other parts of been MFC'd lately without
very much testing if any, noting the panic's that have been accruing on users running
stable for the past 8 months. Should that just be taken as a sign of EoL for RELENG_4 ?


I merged PAE into my version of -current a bit at a time and didn't
notice any problems (with PAE not actually configured) despite having
some large logical inconsistencies from not having all of it.  Most
of the global changes had no effect since they just changed the names
of some typedefs without changing the underlying types in the !PAE
case.  So I suspect that any instabilities in RELENG_4 in the !PAE
case are indirectly related to PAE and/or localized and thus easy to
find and fix.

Right the fix(es) should be trivial though incredibly hard to track down.
Even more so that FreeBSD no long has anyone that is qualified to do
any real work on the VM system. It is ridicules that re@ has allowed PAE
to stay in the STABLE branch for still long with the amount of instability that
it has created. I know its just uncovering bugs in the system that have always
been present. Now we have many many kernel stack trace's and should be
able to track it down over the next week months.


For now though, the PAE commit should be removed from the RELENG_4 tree.
Anything else should be not excepted  by the FreeBSD community.
