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
http://lists.infradead.org/pipermail/linux-mtd/2005-January/011517.html
may help.
