Running the 2.4.20 kernel, after a power outage 2 of my test units get boot
message mount errors:
jffs2_scan_dirent_node(): Name CRC failed on node at 0x00b620c8: Read
0x640c8ca3, calculated 0x795111fe
jffs2_scan_dirent_node(): Name CRC failed on node at 0x00eaf1e0: Read
0x16f2116a, calculated 0x0622ba51
The units seem to boot fine, but I'm sure there are probably files I can no
longer access on the file system.
Is this possibly from JFFS2 running garbage collection when the power is
removed? Is there an MTD utility to fix this corruption _while_ the ROM is
mounted? Is there a work around ( like running "sync" every 5 minutes in
cron )?
Thanks,
-Brian

So, should the garbage collection eventually fix it by itself?

Brain, I've just added the corresponding entry to the JFFS2 FAQ, please,
read it. If it is vague - ask.
