I wonder what is the meaning of the tow numbers after a function 
name.

You can use objdump -dSl foo.ko to get the exact line that failed. Look 
at the left hand column of the dump and match it with the first hex 
number in your trace. The objdump command may take a while if your 
module is large. Obviously you'll need debugging symbols built into the 
ko.
