Hi Stefan, Thanks for these patches, I apologize for the time it took for us to respond to this. The first patch is functionally correct, and I'm surprised we missed sending an equivalent ourselves. It looks like some related changes occurred around this code, and we failed to submit the patch. I think Jeff would prefer if we send the version based directly on the out-of-tree code, which I will be reviving and submitting shortly. The second issue I believe is not fixed correctly by the patch, I'm unsure why exactly changing the WQ would cause this but I believe that a similar patch which creates a non-locked version of i40e_nvm_read_buffer() will resolve this, and I will be sending that patch as well, which I believe is the real fix versus halting the work queue.
