Yup, that'll crash it. Sorry about that. This is another reason why doing the old-style (*agp_find_bridge)(...); is better than doing the new-style agp_find_bridge(...); The former case won't even compile, and is more readable. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

It does the same thing Brice's fix does. Need to put the
one extern struct definition back in agp_backend.h and that is the badness:
