I tried to build my own kernel with PAE option and getting the following error... /usr/src/sys/dev/advansys/advansys.c: In function 'adv_action': /usr/src/sys/dev/advansys/advansys.c:259: warning: cast from pointer to integer of different size *** Error code 1 Any idea what I can do for this error? -- Robert
