I agree with your conclusion here that r8 is 0 at this point. I am very
confused how this can be since the two lines above the ones you pasted
here are:
0x0000000000016683 <iwl3945_rx_reply_tx+291>:»mov (%rdx,%rax,1),%r8
0x0000000000016687 <iwl3945_rx_reply_tx+295>:»mov $0x0,%rdx
>From the information in the post you refer to we have rdx as
0xffffffffa0c85f40 and rax as 0x4f. Since r8 is initialized above from
these two registers ... how could it be that r8 ends up as zero?
