Hi All, Just as I thought I was getting on top of my Gentoo installation on a MacBook, a new kernel oops unpleasantly, although it manages to boot into a Gnome desktop eventually. No wireless is available (broadcom-sta proprietary drive is used). Shutting down/rebooting is a hit and miss operation. Invariably I have to hold the power button to force it to shut down. Shutting the lid does not put it to sleep but goes into some race condition with the fans spinning like mad. The screen is black thereafter until I force it to shutdown.
Previous kernel 4.4.9 had no such problems. I attach the log output. Please let me know if you want to see the kernel .config too. -- Regards, Mick
