UFS Filesystem issues, and the loss of my hair...

[Hearn, Trevor]

Here is the chunk that I grabbed from the screen to save as a memento. :)

As you can see, it's a little disjointed. I would assume that the screwed up length information is from the speed at which it was coming out, and possibly another message got throw in at the same time?

Is the '1638d' above a typo in the cut and paste or does it actually have a
'd' instead of a '4' in the log?  '4' is 0x34 and 'd' is 0x64 so that could
be indicative of a two-bit memory error perhaps?
