Kernel 4.6-rc5 is out, and brief details of changes from -rc4 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.3/00178.html Kernel 4.6 seems to have a habit of continuing later-rc breakages with VMware and NVIDIA, compared to previous kernel releases.. The VMware 12 fix for 4.6-rc4 (see http://rglinuxtech.com/?p=1706 ) still works OK with 4.6-rc5, but even the latest NVIDIA driver – 364.19 breaks … Continue reading →

I had been running Kernel 4.6-rc2 on the Radxa Rock2 without any issues, and decided to update to recently-released Kernel 4.6-rc4.. Brief details of changes from -rc3 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.2/00610.html The boot failed, and I then compiled/installed 4.6-rc3 to see if that would have been OK, and it was..
