I just flushed out tested 4.14 batch, I'll see to get 4.9 > out hopefully tonight as well, and the rest for 4.4 on Mon. While 4.14 and 4.9 BPF backports are tested and out since yesterday, and I saw Greg queued them up (thanks!), it looks like plain 4.4.113 doesn't even boot on my machine. While I can shortly see the kernel log, my screen turns black shortly thereafter and nothing reacts anymore. No such problems with 4.9 and 4.14 stables seen. (using x86_64, i7-6600U) Is this a known issue? Thanks, Daniel
