>Description:
I have three machines which I just upgraded from 5.4 to -CURRENT. They are two SMP desktops and a UP laptop.
After building world and installing, I started to run portupgrade on my systems. On the laptop, everything has been running smoothly.. On both SMP systems, portupgrade hangs. top shows the ruby18 process stuck in the *vnode state. On one machine, which I can't physically access, it's been this way for hours. I can't ssh into this machine, and only have access to sessions that were connected before the hang. On my home machine (which I can physically access), I've been able to log in on the virtual consoles and reboot when this happens (though it's not ever able to sync all buffers and cleanly unmount /). It's now happened with 5 or 6 consecutive attempts at portupgrade on this machine. The most recent time this happened, on a hunch, I built a UP kernel, rebooted, and tried portupgrade again. It ran all night (eight hours) without hanging.
>How-To-Repeat:
Run "portupgrade -r -a" on an SMP kernel (and SMP system) on -CURRENT.
