I tried a3ea3d9b865c2a8f7fe455c7fa26db4b6fd066e3 which is parent of 9d659ae14b545c4296e812c70493bfdc999b5c1c and succeeded to compile kernel. git checkout a3ea3d9b865c2a8f7fe455c7fa26db4b6fd066e3 Then, I compiled kernel and rebooted with it. I tried a couples of times suspending and resuming, all of the time keyboard worked as expected. uname -a Linux ubuntu 4.9.0-rc2reverted+ #1 SMP Sun Oct 28 20:29:39 +03 2018 x86_64 x86_64 x86_64 GNU/Linux awk -f ver_linux If some fields are empty or look unusual you may have an old version.
