Comment 104 for bug 202490

@jerzy, these error messages are nothing to worry about, just missing casts between const and non-const variables. It only happens on 2.6.32

I think I know what was going on.

Please run 'depmod -a', and then try to load the module again.
I would suggest you to read some HOWTOs on how to load and compile kernel modules.

Basicly what the lines:

[ 989.082087] sm_common: disagrees about version of symbol nand_scan_ident
[ 989.082091] sm_common: Unknown symbol nand_scan_ident

mean is that module sm_common (which r852 depends on) can find function nand_scan_ident which I know is defined in nand.ko

So you can try to load module 'nand' manually.
