Bernd Porr, the next step is to fully commit bisect from kernel 3.13 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following

Not that I'm aware of. I had 32bit and 64bit versions running and it was fine. Though I did most development under 32bit prior to 16.04 but some also under 64bit. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

Just tested with 4.8-rc4: no ethernet, no bluetooth at all and graphics defaults to VGA only. Booted back to the stock ubuntu xenial kernel and bluetooth/network is back up running. Looks to me like a massive regression. All tested on an X220 laptop. -- You received this bug notification

Bernd Porr, to keep this relevant to upstream, one would want to test the latest mainline kernel (now 4.8-rc4) as it is released. Could you please advise? ** Tags added: bios-outdated-1.42 kernel-bug-exists-upstream-4.8-rc1 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete
