The purpose of going through a "Reverse" bisect is to identify the commit that fixes this bug and adds the proper CuW B1 device IDs. To do that, we would want to figure out the last kernel that did not have the ids and the first kernel that did.
However, it sounds like all the upstream kernels you tested so far do not exhibit this bug (4.4 -> 4.13), but the 16.04.3 kernel does have the bug? Also, the 16.04.3 kernel should be 4.10 based, but you see version 4.4.0-87? Is that correct? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1715368 Title: Broadcom NXE controller Cumulus devices ID's are missing in 16.04.03 'kernel-fixed-upstream' Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Triaged Status in linux source package in Zesty: Triaged Bug description: Broadcom NXE controller Cumulus devices ID's are missing in 16.04.03.
