PAE was merged into -stable in three steps. Backing out the :third step and leaving the first two steps removes the instability. :Unfortunately, it was the third step that also was the most complex. :In any case, we have 2 weeks to find the resolution before the decision :must be made on keeping or tossing PAE. Since PAE is a *highly* :sought after feature, it would be doing a disservice to our user base :to remove it without putting in some effort to fix it. : I fully agree with the last statement here. One reason my current employer left FreeBSD 4.x and went to linux for our embedded system was due to the lack of PAE support. We were planning to implement the extensions ourself, but, unfortunately, we in engineering were affected by time and money issues. Scott, keep up the good work. Cheers, Andrew -- Andrew R.
