Comment 9 for bug 1726061

To summarize my earlier comments: All the below relates to suspend/resume of 17.10.

Suspend/resume works fine if I boot with the 4.10-based Ubuntu kernel from 17.04, or any 4.13 mainline kernel starting from 4.13.5 .

The mainline kernels from 4.13 through 4.13.4, upon which the Ubuntu kernel is built, all suspend OK but have problems on resume-- the machine comes up but wifi does not connect. Once that happens I cannot reboot or shut down normally, only by holding the power button.

The mainline kernels from 4.13.5 to 4.13.11 resume OK.

The mainline kernels from 4.14.rc1 to 4.14.rc7 have issues on suspend and cannot properly resume -- display does not come on and the machine does not respond to ssh from elsewhere. Again I am forced to hold the power button down for hard shutdown.
