Heh, sorry about not being clear.  What I'm trying to say is that
scmd->device != NULL && device->host == NULL.  Or was this what you
were saying all along?

What I agree with is that the request pointer (req argument) is stored in %rdi
and that mov 0x1b0(%rdi),%rax loads scmd->device into %rax. Since RIP ==
scsi_times_out+0x17, since the instruction at that address tries to dereference
%rax and since the register dump shows that %rax == NULL I think that means that
scmd->device == NULL.

Ah, I was completely confused about which one had to be NULL.  You're
absolutely right.  Let's continue earlier in the thread.

Thanks.
