Problem while going into suspension mode in my Desktop computer

[Biotico1974]

I have a problem when my desktop computer goes into suspension mode on Endeavour Linux. It suspends but then the fans go at full speed and the system is unresponsive. Not even pressing the power or reset buttons does it turn off. I have to cut the power in the power supply. On Windows the problem doesn’t happen so I ruled out hardware issues and started suspecting that it could be some BIOS option or Kernel parameter. I have updated the BIOS to the latest version but the problem still remains. The motherboard is a Gigabyte B550M AORUS PRO (rev. 1.0) running BIOS version F14e and my kernel is 5.15.7-arch1-1.

I never tweaked the power settings on Linux so I’m kind lost

Below is the output of journalctl -b -1 -n100 | eos-sendlog

Would appreciate any pointers to solve this.

I have to cut the power in the power supply.

Don’t do that, you’re just risking filesystem corruption. Enable the magic SysRq key to be able to safely Reboot Even If System Utterly Broken:

[Tip] Enable Magic SysRq Key (REISUB)

The Linux kernel authors have provided a very nice feature of issuing low-level commands to the kernel directly, regardless of the state the system is in. This is called the “Magic SysRq Key”, because these commands are issued by pressing the SysRq key on the keyboard (if you can’t find it, typically, it shares the same physical key as the Print Screen key, but on some laptops it can be elsewhere). A common use is to reboot when the computer freezes and becomes unresponsive due to some software…

As far as your issue is concerned, one way to fix it is to disable suspend:

How to Completely disable sleep/hibernate/suspend?

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Do you need suspend on a desktop? I don’t.

Kresimir ,thank you for your reply.
It tried something new. After the system went berserk if I cycled the power button on the power supply without let it drain all the power ( without making the click sound they usually make) the system comes alive like it suspended normally. I guess the problem must be BIOS related since this board is more or less ‘gaming’ hardware so obviously very windows friendly.
I enabled SysRq and will eventually go for the solution you promoted by disabling suspend completely. I just wanted to understand why suspending on Windows vs Linux got different results.
If I find the solution I’ll post it for future reference.

Thanks and have a great day

I believe I am facing the same issue. Did you find a solution?

At first I had a lot of network issues with Gigabyte B550M using Ubuntu (20.04).
I thought installing an offboard card and disabling lan on bios settings would solve it.
Since that, the machine hasn’t gone offline as it was happening before, but every +2 days on it simply becomes unresponsive.
I also found it difficult to hard reset even with the power button, and a few times taking off the power was the only solution.

I really do not know if it indeed becomes unresponsive, or if both keyboard/mouse simply stop working, as I have seen some posts about them not working with this board as well.

I didn’t find solution and ended doing what Kresimir suggested disabling suspension since I really don’t need it.
In your case I would check if there are any BIOS updates for your board. I never had any network issues although I opted to go with linux device driver r8168 instead of r8169 (Realtek Ethernet controller) since this last one had an history of giving problems.
Hope you find solution to your problem.

Suspension is already disabled in my case. I think it just goes unresponsive no matter what.

Thanks anyway
