Hi, I am facing some non-contiguous write bug in "fs/jffs2/wbuf.c". I have a Hynix 512Mb NAND flash mounted on a board running linuxppc-2.4.20 (gcc-2.96) on an MPC852T processor (Yeah, we are living in the 21st century but cannot afford to port all our drivers to 2.6 if we have to meet the deadline).
I have seen a fix for the 2.6 kernel (http://www.infradead.org/pipermail/linux-mtd/2006-January/014740.html). Do not know how to make the patch work in 2.4.20. Any help is appreciated. Attaching the OOPS messages herewith. Thanks and Regards, Santanu bash-2.03# jffs2_flush_wbuf(): Write failed with -5 Write of %zd bytes at 0x000000a0 failed. returned 8243708, retlen %zd Not marking the space at 0x007dc9fc as dirty because the flash driver returned retlen zero jffs2_flash_writev(): Non-contiguous write to 007dc9fc wbuf was previously 007dc800-007dca00 kernel BUG at wbuf.c:305!
