Title:
Repeatable hang within 5 minutes using stress-ng + sleep + usb mouse
Status in xorg-server package in Ubuntu:
Confirmed
Bug description:
If I run a thermal transition test script (30 seconds stress-ng, 30
seconds sleep, in a loop) and move a local USB mouse, Kubuntu reliably
crashes, usually in the first couple of runs and almost 100% of the
time by run 6.
This appears to be hardware-linked, but not due to a specific piece of
bad hardware: I have swapped literally every piece of hardware in the
system.
It shows up (while running the script at the end):
- On both an MSI B450 Gaming plus max and MSI MPG X570 Gaming plus mainboard.
- On both an AMD Ryzen 5 3600 and 3600X CPU.
- With one or two sticks of RAM. I've tested both sticks individually, in
more than one mainboard slot.
- Regardless of whether the mainboard is in/attached to a case.
- Regardless of whether there is an m.2 SSD installed or I'm running off a
live Kubuntu 19.10 USB stick with no hard disk attached.
- Regardless of which of two mice I use (an old Logitech one, or a GTX 133
Gaming mouse).
- Regardless of whether I'm using a Corsair VS650 or Corsair AX850 PSU.
- Regardless of whether I'm using an AMD RX 5700 XT or using an Nvidia
Gigabyte GeForce RTX 2700 Super (with open source drivers in both cases).
- Regardless of whether I'm using KDE or XFCE.
- Regardless of whether I'm using the default KDE DM or switch to GDM3 and
set WaylandEnable=false.
- Regardless of whether I use the default 5.3.0-29-generic kernel or
5.4.17-050417-generic.
- Regardless of whether I go directly into the graphical environment or start
in runlevel 3 and then manually run startx.
- Regardless of whether it's on the rising or falling edge of the
stress-script's temperature changes.
- Regardless of bios version on the X570 mainboard (the one it shipped with,
or the newest one released in January 2020).
- Regardless of whether XMP is on or off in the bios.
- Regardless of whether I use the default or set global c-state to "control =
disabled" in the bios.
- Regardless of whether I add processor.max_cstate=5 idle=halt in grub.
- Regardless of whether or not speakers are plugged in.
- Regardless of whether I'm using a USB port that is directly on the
motherboard or is on the front of the case.
- Regardless of which monitor it is attached to.
It doesn't show up:
- On an old i7-4771 machine I have, also running Kubuntu 19.10, while running
the test script.
- When I use a mouse remotely with ssh -Y [ip of the machine I am reporting
this from] xeyes, while running the test script.
- When I do non-mouse USB input, ie via a USB keyboard or USB wifi dongle,
including under saturated network load, while running the test script.
- During stress tests of the GPU, CPU, etc. Tools like memtest, mprime,
Unigine Superposition, repeated kernel compiles, etc run stably overnight.
- When the system is entirely idle aside from mouse movement.
- When I start in runlevel 3 and run the same test script, using the mouse
with gpm.
- Running the same test script without mouse movement: this was stable
overnight, then crashed within a couple of minutes of moving the mouse.
It shows up with load other than the stress-ng+sleep script too, but
much less reliably - I'm writing this bug report on the relevant
machine, with firefox open. Crashes occur at least once a week under
these conditions, but not frequently.
Crashes occur with sensor-reported CPU temperatures of 32 to 41
degrees Celsius. Nothing is overheating, and the system is stable at
much higher temperatures under sustained stress tests.
The symptoms of the crash: the display stops updating and the system
does not respond to any further input, including via the network or
magic sysrq key. There is nothing related to it in syslog or
journalctl, including when I'm running journalctl -f at the time of
the crash.
The test script:
#!/bin/bash
for x in {1..10000}
do
echo "Run $x at `date`"
stress-ng --cpu 12 --cpu-method all --verify -t 30s --metrics-brief
sleep 30
done
