Node CRC failures in latest mainline git?

[Bill Gatliff]

Guys:


I pulled from Linus' tree yesterday, and all of a sudden I'm seeing a _ton_ of
these:

JFFS2 notice: (224) jffs2_get_inode_nodes: Node header CRC failed at 0x263a0fc.
{1985,c002,00000046,32fe3396}

An older kernel (three or four weeks ago) continues to work fine on the same board.

The target is a PXA270 with a Spansion 29GL512N.  The kernel was built with
arm-linux-gnueabi-gcc (GCC) 4.2.4 (Debian 4.2.4-3).  There haven't been any
changes in the mtd-related parts of the kernel, other than what's come in from
Linus.

It looks like the most recent mtd-related commit is this:

$ git-log drivers/mtd

Were I more competent with git, I would figure out how to bisect down to the
patch that caused the problem.  That's still a bit out of my skillset at the
moment, unfortunately--- I've done bisects successfully in the past, but for
some reason I just can't get git to play along this time...


Thanks!
