This has to be related to a smilar bug with raidframe.

The disk geometry is reported as 119150 cylinders, 16 heads, 63 sectors.
I suspect this means that the ufs filesystem has a very large number
of cylinder groups.

The directory placing algorithm doesn't work well under these circumstances!

Recent changes to newfs (with the ufs2 support) mean that it ignores
the physical geometry so these problems won't happen any more!

Anyone know if the modified newfs is actually compatible with the old
filessytem code?
