Suspend fails. System suspends and then immediately restarts

[beaucoder]

Hi All

Suspend was working well for weeks. After an update suspend now goes into suspend but immediately restarts.

I tried from the terminal with ‘systemctl suspend’ and it worked perfectly but only once. Normal Gnome Suspend and terminal manual suspend no longer work.

Using Manjaro 24.2.0. Tried linux kernels 61, 611, 66. No success

For many weeks suspend worked unfailingly. A few weeks ago Firefox would lock up from time to time requiring a reboot. Then suspend began to fail.

It suspended but immediately restarted. I am on Wayland with Manjaro(Gnome).

• Turning Gnome extensions off has had no effect. On kernel Linux 6.11.10-2-MANJARO.

Kindly advise.

Thanks,

Hello beaucoder, I don’t have an answer for your problem, but have you looked at the kernel ring log messages for any clues? You can do this with the following command:

sudo dmesg

You may consider including more detail about your system that may help others troubleshoot your issue.

[HowTo] Find system information

Difficulty: ★☆☆☆☆ Rather than providing the commercial reference of a computer or piece of hardware, it is usually better to directly ask the system to describe itself. On top of saving time to everyone, this also often provides more details, including something specific to the running system. Below is a (not exhaustive) list of commands for retrieving system information. If you don’t know how to use those commands, or how to provide them to support, see: [HowTo] Use the terminal / TTY …

Regarding I would say to always provide the full output from sudo inxi --filter --verbosity 8 as that is usually far more helpful information than people summarize in their requests for help.

I did check the Arch Wiki for anything on “instantaneous wakeup after suspending”, and did find some interesting information, but for other motherboards, so probably doesn’t apply to your situation. Still, you may find this worth researching:

For some Intel Haswell systems with the LynxPoint and LynxPoint-LP chipset, instantaneous wakeups after suspending are reported. They are linked to erroneous BIOS ACPI implementations and how the xhci_hcd module interprets it during boot. As a work-around reported affected systems are added to a denylist (named XHCI_SPURIOUS_WAKEUP) by the kernel case-by-case [3].

Wakeup may happen, for example, if a USB device is plugged during suspending and ACPI wakeup triggers are enabled. A viable workaround for such a system is to disable the relevant wakeup triggers. An example to disable wakeup through USB is described as follows… Power management/Wakeup triggers - ArchWiki

After a few more updates suspend has started working properly again.

Thanks for your reply.
