I have been seeing something on shutdown once every 10-20 times or so but it went by so fast I couldn't tell what was happening. I set up a serial console on the kernel command line, directed it to a file in VMware, and tail it in another window. It's like having a separate console monitor from the 80's. Here's a snippet:

I haven't seen this on 64-bit yet, or any previous version that I boot into. I have used this VM to boot TCL versions 8-17 32 and 64 bit so I'm pretty sure it's not the virtual disks themselves, especially since it's the same error on two different disks.
