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?
