Linux booting problem when initializing flash file system

[Atit_Shah]

Hi All,

	I am using a board which has a ST Micro Electronics Flash
(M29W640DB) and when booting the Linux Kernel I get the following error:

jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000:
0x0020 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000004:
0x22df instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000000c:
0x0008 instead

Further such events for this erase block will not be printed
JFFS2: Erase block at 0x00000000 is not formatted. It will be erased
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00020000:
0x0020 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00020004:
0x22df instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0002000c:
0x0008 instead

And it ends with................

Cowardly refusing to erase blocks on filesystem with no valid JFFS2
nodes
Kernel panic: VFS: Unable to mount root fs on 1f:00
<0>Rebooting in 180 seconds..

The reference board using an AMD flash works fine. I selected the ST
Flash from make xconfig in Linux but the kernel crashes before it even
calls start_kernel.
Could somebody suggest wrong....

Thanks
Atit
