While doing powercycles with an OMAP3 board I got several strange
effects on my board.
So even when mounting the root-partiton as read only ( ... noinitrd
root=/dev/mtdblock6 ro rootfstype=jffs2 ... ) I 've got sometimes (1
in a 100 trials) a bunch of message while mounting:
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00260000:
0xff30 instead
And later on
JFFS2 notice: (365) jffs2_get_inode_nodes: Node header CRC failed at
0x260090. {6144,773c,840fc11a,cc0c0e28}
Another time I get a
uncorrectable error :
Which is coming from nand_ecc.c (this is below the filesystem I guess).
The strange thing is, this errors/messages are disappeared in the next boot.
I suspected the RAM/Flash hardware but on the other hand it unpacks
the kernel a few 100 times, but never get a CRC error.
Looking into kernel sources I found special omap2.c with some nand
related code. I am using a standard 2.6.33 kernel.
Does someone have a good advice what the reason for that might be. Any
help is welcome.
