Intel 28F128 - Linux-2.4.24 broke jffs2 v2.2?

Mon Feb 16 17:36:40 EST 2004

Hi,

For about a year I have been using Kernel 2.4.20 + JFFS2 v2.1, and am
attempting to upgrate to 2.4.24 and the CVS from 14 Feb 04.  I am getting
some strange debugging values.  It looks like the Intel flash is in "Read
Identifier Codes" mode, rather than "Read Array" Mode.

The jffs2_scan_eraseblock() output seems to be consistant regardless of
changes made to the kernel config.

Below my sig is the boot output with MTD debugging =  3 / JFFS2 = 2

Any help would be appreciated.

Thanks,

-Brian T.
