Just updated the test system to Kernel 4.14.10, and was ‘somewhat dismayed‘ – to put it politely – that the NVIDIA breakage introduced in 4.14.9 is still there!

So… the 4.14.9 patch still applies, and fixes the problem (see http://rglinuxtech.com/?p=2168 ):

Its not as if the kernel devs weren’t told…  http://lkml.iu.edu/hypermail/linux/kernel/1712.3/02196.html

Oh well, maybe in 4.14.11??
