Hi,

We have been using PPC with a AMD flash (Spansion S29GL128M) on it for our
applications.  We are running Montavista linux on it.  Recently we replaced
the AMD flash with ST flash (M29W128FH).  The u-boot boots up and during the
kernel boot, I am getting the following error messages and the system
doesn't boot after this:


jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000:
0x0020 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000001c:
0x2212 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000020:
0x0020 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000003c:
0x2212 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000040:
0x0020 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000005c:
0x2212 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000060:
0x0020 instead

It would be really great if someone could let me know what is going wrong in
this.

Thanks,
Ganesh
