/dev/mtdblockX works fine, but /dev/mtdX NOT.
Did you only create mtdblocks or mtds too?
Older MTD creates /dev/mtdX with minor numbers X*2; running flash_erase
(for example) works fine.
Not so with same kernel, but latest CVS: creating exactly the same
/dev/mtdX as mtdchar.c would do (e.g. older MTD would do), I cannot
operate the flash properly. flash_erase results in an CFI error:

Hm...
