It means the driver for the chip's connection to your board (probably) 
isn't raising the voltage to the proper level (called VPP in the mtd 
code) required by the chip for an erase operation.  Various code paths 
can nest VPP enables/disables in unbalanced ways, often causing 
problems.  If this is the case in your situation, info in
may help.
