By the way, I connected back up the sound on my machine before that most
recent crash. So, it is not the cause (for anyone who may have
considered that possibility).
Also, you will find this possibly relevant thread regarding
smp_call_function_ (single or many):
I have had 3 hangs between 24 March and 1 April. All were when I was
out and about, so I couldn't SSH into the machine.
Today, I had a couple of hangs occur with no apparent cause. Disk
activity continued. But, I couldn't SSH into the machine.
I killed the machine (during a hang) at 8:35:51
It hung again yesterday (S 23 Mar 2019). It used to hang multiple times
daily.
Anyhow, the laptop was unresponsive. The disk activity light continued
as normal, though.
However, it did allow me to SSH into it, but hung completely when I
tried to open gnome-control-center. That suggests that
Err, the issue sounds a lot like Bug #1743094. Maybe one should be

I forgot to mention that before demonstrating that "Night Light" and
"Dim screen when inactive", I upgraded to the latest BIOS from Lenovo on
20 March (a day prior to posting #16 and before turning off the dimming
features). It is the Lenovo 85UJ25US (1.46) BIOS, which is an upgrade
from 8BET55WW
By the way, this issue appeared on my machine, which is a Lenovo W520.
I have turned off automatic suspend while plugged in. I need it to run
financial calculations overnight. And, I have increased the battery
power delay to 30m. Though that is neither here nor there.
With "Night Light" and
I've found that I can make the system stable with the following
settings:
System Settings:
Privacy>Screen Lock:On
Power>Dim screen when inactive: Off
Power>Blank screen: 10m

Just wanted to share my observations.
At least on my machine, "failed resumes" are appearing in series after
initial BSOD (black screen of death), which usually occurs after a long
suspend.
After some experimentation, I've found that full/proper shut-down and
boot-up cycle (in addition to the

I noticed the existence of this error during the boot: "nouveau : 01: 00.0:
bus: MMIO read of FAULT at 612004 [IBUS]".
So I decided to search and found a suggestion to include the following
parameter in the kernel command line "nouveau.modeset = 0". So I decided to
test it and

However, whenever I suspend and resume, at least once, when I try to shut down
the system hangs and only accepts REISUB or forced shutdown.
Besides that, I lost the functionality of

After some tests I discovered that, in my case, the locking is related to
wireless. By disabling the wireless network the problem disappears, it suspends
and returns normally.
So, as a test, I deactivated the power saving, as suggested in the link
Same fault with Dell Inspiron 5557. On resume it takes about 4 seconds
and then the lock screen appears, when trying to unlock it accepts four
to five digits and then hangs completely (nor REISUB works). The only
option is manually power off.

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16
I'm seeing messages in syslog that show USB device(s) not reconnecting.
I spoke to Jamie and his monitor is connected over a USB-C dock. That
might be involved here.
