(Only disabled this one option - see diff between .config.old and .config below) I don't see this issue on my SDP even with OMAP_FB enabled. May be we have different ES versions Thanks for testing - switching to a different filesystem, the crash goes away. But I'm still not sure what caused the crash to disappear with the old filesystem but with CONFIG_FB_OMAP removed.
