Still no luck. I tested it together with the macronix patch and it
throws the same error.
[ 0.936695] CPU 0 Unable to handle kernel paging request at virtual
address 0040000c, epc == 80064ff0, ra == 80066fd4
[ 0.947583] Oops[#1]:

[ 0.956087] $ 0 : 00000000 00000001 00400000 00000002
.....
Thanks for the suggestions.
