Re: 4 significant issues with amd64 -current

Now that the ahcisata issues with the first drive not probing correctly seems to be ironed out (thanks!), I figured I'd update my Feb 11th -current to May 11th. An install on a VMWare system worked fine, so I had high confidence in it working on my home server. Unfortunately, I had to roll back to Feb 11, due to the following 4 issues:

Issue 1:
Neither root nor a normal user can login. More precisely, entering proper credentials on either the serial console or via ssh seems to work, insomuch as I see the NetBSD banner, and the requisite "You have new mail" line. But then instead of a shell prompt, I'm returned to the login prompt. I can't find anything in authlog (which makes sense, since I did seem to authenticate properly!) or /var/log/messages. This one has me utterly stumped.

Issue 2:
In single-user mode (since I can't login in multi-user...see above), "vipw" reports that it cannot find /usr/bin/vi (no such file or directory). Of course, "vi" does reside there, and works fine. Comparing a ktrace on my VMWare installation and one on my real system shows everything identical up to:

It looks like both of these issues are due to a regression in PAX_ASLR. Setting that to zero works around these two issues.
