Comment 4 for bug 1748408

@Joseph: I did test 4.15.2, but some things are failing, in particular docker because of lacking AUFS support, so I need to build a kernel myself I guess, which will take a bit.

Also note that I'm seeing this on Xenial machines, didn't test with Artful. We used to run them with the 4.10 HWE kernels because they offer improved performance in some areas compared to the stock 4.4. kernel. Started seeing these issue after HWE switched to 4.13 a couple of weeks ago.
