System unusable after resuming from stand-by

Ask Fedora
1

I am running Fedora 41 with kernel 6.11.10 and KDE Plasma 6 on a Lenovo Yoga Slim 7 Pro X model 14ARH7, the variant with a Ryzen 7 6800 HS, and 512 GB Samsung SSD. The UEFI is up-to-date.

Every time the system is resumed from standby, it freezes permanently within a few seconds. At this point, the only thing to do is switch off the PC using the power button.

The first thing I did was consult the Arch Wiki, which mentions a problem regarding the SSD controller and, as a solution, adding iommu=pt to the kernel parameters. That didn’t work.

Then, I found a discussion in which it appears that the problem is related to a bug in the Samsung SSD controller, that should have been solved by now, but in my case, the fix does not seem to be effective.

I searched for other information but without any luck. Also both journalctl and dmesg -w didn’t reveal anything that I could use. I also tried the CachyOS kernel 6.12.2 as a last resort.

At this point, I do not know what to do, and it is pretty frustrating not being able to use the stand-by.

Show us the output of inxi -N.

If you have a Mediatek wifi/bluetooth chip then it’s likely you’re hitting the issue described here:

Output of inxi -N:

    driver: mt7921e

In the liked discussion a user proposed a service to disable Bluetooth before stand-by. Unfortunately, it doesn’t seem to work, the system still hangs after standby.

Edit: a user tested kernel 6.12 successfully. I will try that.

Tested kernel 6.12.3. The problem is still present

I don’t know if it can be useful, but here are the journalctl logs of the time when the system hung after standby
