There're only two entries that will run to ffffffff80b10416, one is > ffffffff80b103a0: 48 85 f6 testq %rsi, %rsi > ffffffff80b103a3: 75 64 jne 0xffffffff80b10409 , the another one is > ffffffff80b103fe: 48 8b 78 20 movq 0x20(%rax), %rdi > ffffffff80b10402: eb 08 jmp 0xffffffff80b1040c So I suspect the line number 850 by kgdb is wrong, and the correct one shou= ld be 861. I have no evidences but may you please have a try with the patch ? --=20 You are receiving this mail because: You are the assignee for the bug.=
