This has been reported by people, and it has been fixed by later post. The commits within linus's tree are: commit 6df77862f63f389df3b1ad879738e04440d7385d Author: Baoquan He Date: Sun Nov 13 13:01:33 2016 +0800 bnx2: Wait for in-flight DMA to complete at probe stage commit 5d0d4b91bf627f14f95167b738d524156c9d440b Author: Baoquan He Date: Sun Nov 13 13:01:32 2016 +0800 Revert "bnx2: Reset device during driver initialization" This reverts commit 3e1be7ad2d38c6bd6aeef96df9bd0a7822f4e51c. And I believe both of them also are picked up into 4.8-stable kernel. Please have a way to get them. Sorry again!
