Unable to handle kernel paging request at virtualaddress80000013

[Eric DEJONC]

Thank you all for your help,
I gave the vmlinux file but  compiled with the cross compiler I  think it was
the right think to do, i gave too the system.map and the sykms. The output
seems to denote that the problem comes from the jffs2, driver?

I'd be gratefull to you if you could give me your opinion.

Best regards,
Eric
