I've been trying to build userland repeatedly over the past few days on
a particular machine and consistently get kernel panics, though never at
exactly the same point in the process. The latest occurred midway
through 'make obj'. Attempts to build userland on another i386 machine
from code pulled via cvs at more or less the same time works fine, so it
seems the issue is isolated to this hardware.
I initially suspected my SSD had gone bad, so I replaced it with a brand
new drive. However, the issue persists, so I no longer suspect the drive.
A ps, trace, and dmesg are provided below. This is my first reporting a
bug of this nature. I hope I've followed procedure. If not, please do
let me know. I'm trying to be useful. :-)
