Steps for reproducing this issue:

  1. Open a game
  2. Put the device to sleep and wait some time (not sure how long)
  3. wake up and resume the game.

you are better off submitting a system report (Settings -> System -> Advanced -> System Report -> Create Report) after the issue occurs since it's hard to tell what's going on in there, and the report will include complete logs for what happened.

Dec 07 16:34:38 steamdeck kernel: CR2: 00007fc4d28a3f30 CR3: 0000000148886000 CR4: 0000000000f50ef0

the error -110 messages look very similar to #2037, and eventually in your case it cascades into a bunch of kernel warnings and errors relating to ext4.

your SD card reader is O2 Micro, Inc. SD/MMC Card Reader Controller [1217:8621], which is different from the one in my Windows Legion Go S model so there must be multiple types in different models.

I'd be interested if upcoming SteamOS preview builds that are based on a later kernel version help your case or not. Or, you can switch to the "Main" branch of SteamOS to try the kernel there now, although this is the development branch and prone to be unstable at times.

Replying to https://github.com/ValveSoftware/SteamOS/issues/2233#issuecomment-3623783348

Thanks for the info — yes, mine is the SteamOS Edition of the Legion Go S, so the SD card reader being different from the Windows model makes sense. In my case, the issue only appears with a 2TB SanDisk Extreme Pro; a 512GB Samsung card works fine. Since your model uses a different SD controller, do you happen to have a large-capacity (1TB–2TB) card to test suspend/resume with? It would be useful to know if the problem only shows up on the SteamOS Edition hardware.

The logs I’m seeing (mmc0: Card stuck being busy, error -110, followed by a full re-enumeration and ext4 journal recovery) all happen very early during resume, before user-space starts. Because of that timing and the hardware-level disappearance, I’m currently leaning toward this being related to how the SteamOS Edition BIOS handles SD power or wake timing.

I can try the upcoming SteamOS preview builds or switch to the Main branch to see if a newer kernel changes the behavior.

I have this specific card as well, and it's what I've been doing the majority of my testing with.

I have the Legion Go 2. The model of the SD Card Reader is RTS525A. With the 1.5TB SD Card there are no issues, but if I use the 2TB one, I get freezes/disconnects.

Ran the dmesg command and saw cannot verify signal voltage switch followed by a -110 error. The issue is present on both SteamOS and Bazzite. Windows is fine. Definetly a Driver issue. Saw many people online report problems with this model of the Card Reader.

Additional data point: after reformatting the SD card and only downloading a small number of games, suspend/resume works reliably. Once the card has >1 TB of data on it, the suspend/resume issue starts reproducing consistently. The failure behavior is the same as before.
