something wierd mounting a disk on CAMBRIA

[John Hay]

Hi Guys,

I built a new -current for CAMBRIA, put it on the nfs server, the new
kernel in the tftp area and booted my CAMBRIA board. That worked just
fine. Then I cleared and formatted the Compact Flash that was plugged
in, hoping to be able to make a boot disk. Having done this a few times,
I have it scripted, but have not done it in a few months. This worked
up to and including the mount of the disk without errors. Except after
mounting, the disk was not accessable. Is there something new one have
to do or did I stumble on a problem?
