Hi Andrew,
The machine do not have the mtd device, and the mtd is compiled into the vmlinuz.
This configuration works fine for other kernels and is reproducible with
2.6.23-rc9 only.

Hi Andrew,
The machine do not have the mtd device, and the mtd is compiled into the vmlinuz.
This configuration works fine for other kernels and is reproducible with
2.6.23-rc9 only.
