Does booting back with the Xenial kernel make the bug go away? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

[kswapd0:50]; oom-killer; and eventual kernel panic on 16.10 (upgrade from 16.04) Status in linux package in Ubuntu: Incomplete Bug description: I have a Dell (PowerEdge T110/0V52N7, BIOS 1.6.4 03/02/2011) was running Ubuntu 16.04 for a while. Ever since I upgraded to 16.10, this problem started with errors, OOM and an eventual kernel panic. It can run fine for about 3-4 hours or so. I see the following errors on syslog (also attached w/ other logs and information I can gather). Jan 9 07:36:32 gorilla kernel: [69304.099302] NMI watchdog: BUG: soft lockup - CPU#1 stuck for 22s!

Removed the external backup drives to isolate the problem. Checked similar issues on lanchpad.net but most of them are related to video driver and power supply. Appreciate help.
