I can get a "strace -xvf blkid" trace file if that would

I was just going to suggest something like this. Once it's hung, it's
usually too late to strace it. You need to run it with strace to start
with.
Try "strace -s200 -f -o blkid.trace blkid". That will generate a file
called "blkid.trace" in the current directory containing all the output.
Once it's hung, you should be able to ^C it. Check the last lines of
that file to see what it was trying to do at the point it got stuck.
