What does it mean to provide "more info" about a print statement from
the driver? Is there a Kconfig which he needs to set to get more info?
Perhaps you should provide a debug patch he can apply on his tree, that
will print info about (1) which buffer mapping failed (head or frags);
(2) what the physical address was of the buffer that couldn't be mapped.
