ubi_bgt0d: page allocation failure. order:8, mode:0xd0

[Eric Millbrandt]

Hello all,

I have an embedded system that is running on a ubifs root filesystem which is dropping into read-only mode.  After a read of the mtd FAQ I found out that the filesystem has an unexpected error and that I should contact this list.  What could be causing this error?

I am running the following

- Freescale MPC5200B
- Micron MLC NAND flash
  - data lines attached to the LocalPlus Bus
  - control lines attached to gpios
- A custom MTD NAND board driver that maps the gpio/control lines to the upper MTD layers

The board driver was validated against the MTD tests.

Here is a snip of the relevant kernel messages
