Help with 2.4.22 MTD driver

[Frank R Callaghan]

Hi All,

I have been using 2.4.19 + mdt patches for sometime with no problem, now
I must switch to 2.4.22 and I have a problem with MTD 

The kernel seem to detect the chip correctly:

physmap flash device: 200000 at 9400000
 Amd/Fujitsu Extended Query Table v1.1 at 0x0040
number of CFI chips: 1
cfi_cmdset_0002: Disabling fast programming due to code brokenness.
mtd: Giving out device 0 to Physically mapped flash
Using physmap partition definition
Creating 2 MTD partitions on "Physically mapped flash":
0x00000000-0x001e0000 : "fixed_flash"
mtd: Giving out device 1 to fixed_flash
0x001e0000-0x00200000 : "BIOS-DO_NOT_TOUCH"
mtd: Giving out device 2 to BIOS-DO_NOT_TOUCH

but latter:
.......................
.......................
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x001e0024: 0x7265 
id
Further such events for this erase block will not be printed
JFFS2: Erase block at 0x001e0000 is not formatted. It will be erased
................... repeated for tree more blocks

cat /proc/mtd gives:

dev:    size   erasesize  name
mtd0: 00200000 00010000 "Physically mapped flash"
mtd1: 001e0000 00010000 "fixed_flash"
mtd2: 00020000 00010000 "BIOS-DO_NOT_TOUCH"

I'm not sure if this correct as before with 2.4.19 it looks like this

# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 001e0000 00010000 "fixed_flash"
mtd1: 00020000 00010000 "BIOS-DO_NOT_TOUCH"


Now the flash file system on the partision is corrupt :(

can someone please give me a little guidance on how to find the problem ?
what other info would help ?

Thanks In Advance,

	Frank.
