I was one the people who were experiencing stability problems after the PAE commit. I had several unexpected panics and could provoke panics nearly at will on systems that had previously been rock-stable. After the Aug 30 commit I have not had any panics at all and I have not experienced any other stability problems either since then. In my personal experience RELENG_4 is currently quite stable (not counting any commits made during the last 48 hours or so since I have not yet tested any of those), but it is of course possible that other people have run into bugs in components of the kernel that I don't use. (Note: I do not have PAE enabled in the kernel. I have no idea what the situation is for those who actually have enabled PAE, but any problems that may exist there is non-critical IMO since they would not affect any pre-existing configurations.) -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
