Robin, I looked at it, and it looks like the reading of cylindar group 
185 is the culprit.  Without fsdb usable, it's hard to attempt fixing. 
I think the routine that attempts to alloc memory needs to be tweaked to 
recognize ridiculous numbers, but I'm not sure the best way to do it - I 
suppose for this case, one could just truncate at some ceiling to get 
past it, but that would definitely be the wrong thing to do, and 
dangerous too most likely.

I've cc'ed the -fs list, and bcc'ed the -isp list, since this is a 
filesystem issue, and more people with fs-foo will be able to chime in.
