Checking in again, no real changes in my observations of this bug. It's worth noting that this only occurs in 0.5% of our machines (yes, half a percent!). A good chunk of them are servers with DRACs, but there's a nontrivial amount of desktops that hit this issue too.
I'm having affected users try running the linux-generic-lts-xenial kernel to see if that makes the issue go away. Will update this bug with my findings.
