Sorry for pasting the decoded output twice in the last message. Here is what gdb shows for nvidia_gpio_setsda. c020c94d(gdb) x/30i 0xc020c94d 0xc020c94d <nvidia_gpio_setsda+29>: mov %dl,0x3d4(%eax) 0xc020c953 <nvidia_gpio_setsda+35>: mov 0x900(%ebx),%esi 0xc020c959 <nvidia_gpio_setsda+41>: movzbl 0x3d5(%esi),%eax 0xc020c960 <nvidia_gpio_setsda+48>: movzbl %al,%eax 0xc020c963 <nvidia_gpio_setsda+51>: mov %eax,%edx 0xc020c965 <nvidia_gpio_setsda+53>: and $0xe0,%eax 0xc020c96a <nvidia_gpio_setsda+58>: and $0xf0,%edx 0xc020c970 <nvidia_gpio_setsda+64>: or $0x10,%edx 0xc020c973 <nvidia_gpio_setsda+67>: cmpl $0x0,0xc(%ebp) 0xc020c977 <nvidia_gpio_setsda+71>: cmove %eax,%edx 0xc020c97a <nvidia_gpio_setsda+74>: movzbl 0x4(%ecx),%eax 0xc020c97e <nvidia_gpio_setsda+78>: or $0x1,%edx 0xc020c981 <nvidia_gpio_setsda+81>: inc %eax 0xc020c982 <nvidia_gpio_setsda+82>: mov %al,0x3d4(%esi) 0xc020c988 <nvidia_gpio_setsda+88>: mov 0x900(%ebx),%eax 0xc020c98e <nvidia_gpio_setsda+94>: mov %dl,0x3d5(%eax) 0xc020c994 <nvidia_gpio_setsda+100>: mov 0x4(%esp),%esi 0xc020c998 <nvidia_gpio_setsda+104>: mov (%esp),%ebx 0xc020c99b <nvidia_gpio_setsda+107>: leave 0xc020c99c <nvidia_gpio_setsda+108>: ret 0xc020c99d <nvidia_gpio_setsda+109>: lea 0x0(%esi),%esi 0xc020c9a0 <nvidia_gpio_getscl>: push %ebp 0xc020c9a1 <nvidia_gpio_getscl+1>: mov %esp,%ebp 0xc020c9a3 <nvidia_gpio_getscl+3>: mov 0x8(%ebp),%eax 0xc020c9a6 <nvidia_gpio_getscl+6>: mov (%eax),%ecx 0xc020c9a8 <nvidia_gpio_getscl+8>: movzbl 0x4(%eax),%edx 0xc020c9ac <nvidia_gpio_getscl+12>: mov 0x900(%ecx),%eax 0xc020c9b2 <nvidia_gpio_getscl+18>: mov %dl,0x3d4(%eax) 0xc020c9b8 <nvidia_gpio_getscl+24>: mov 0x900(%ecx),%eax 0xc020c9be <nvidia_gpio_getscl+30>: movzbl 0x3d5(%eax),%edx
