System freezes randomly after upgrading to ubuntu 17.04

[Luke picciau]

Since upgrading to ubuntu 17.04 from 16.10 my system will randomly freeze after a few hours. Initially the display will stop updating then audio will stop playing. Nothing but a hard reset can fix it. I have attempted to switch TTY and use alt+sysreq+1 then alt+sysreq+t still nothing.

I can't work out how to reproduce this issue but it happens seemingly randomly fairly often sometimes while the computer is not in use and locked. I tried switching from unity to gnome to solve the issue but I have the same problem.

Here are the lines in syslog right before the crash

I will also attach the output from lspci

Had another freeze but while it was stuck I got a notification so the display isn't stuck. The mouse and keyboard don't work anymore but remain lit up. The power button also doesn't work even though it is set to suspend the system.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same behaviour except that I usually can move the mouse within one screen (dual-screen system). No reactions on mouse clicks or keyboard input. Ctrl-Alt-F1 does not work. REISUB works and can power down the system! So the keyboard is not really dead.

Suspicious lines from syslog:
 * NMI watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [thunderbird:2634]
 * CPU: 0 PID: 2634 Comm: thunderbird Tainted: G D L 4.10.0-20-generic #22-Ubuntu

I have no idea whether they are related.

uname -a says "4.10.0-20-generic #22-Ubuntu SMP Thu Apr 20 09:22:42 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux".

Hope the following description belongs to this bug, couldn't easily find something more similar:

After a fresh install of 17.04 (with standard packages) on my Dell Latitude E7240 some 10 days ago, my system seems to show similar phenomena, however, I could recognise that the final freeze is a consequence of a staged process happening beforehand:

1. E.g. (T)hunderbird or (F)irefox is getting what is (afaik) called a Zombie process, however, instead of "Z", T/F are marked with "D" (for disk) in top, running at 100% and not killable via top or kill -9/-15.

2. Machine load is slowly going upwards (within 4-5 min or so) until I can't switch windows or desktops anymore, neither can I switch to the text console to initiate an ordinary "shutdown (-R) now".

3. I have to perform a hard ACPI reset per button.

This happened already 4 times since I have installed 17.04.

According to what I found on the web,
https://unix.stackexchange.com/questions/5642/what-if-kill-9-does-not-work
it seems to be a peripheral/driver/filesystem/interrupt related problem. However, this exceeds my knowledge.

Hope to get some help, or hope to have contributed worthy information.

This seems to be a duplicate of bug 1674838 (but since it doesn't contain the dmesg or kern.log info about the kernel panic, I'm not sure if this happens at swapops.h:129 as well).

I have this problem under Ubuntu 17.10, with the same line right before a total freeze and audio loop:
