RE: [Ltib] Old uImage Won't Boot

[seh]

Hi Carolyn,

Look on the nfsserver in /var/log/messages (or ??) to see if it has
anything helpful in there.

Also, try on another machine (not the target) to nfs mount that directory
and then as root try creating a file.  This should prove whether or not
the nfs export is working as it should.

Regards, Stuart
