Kernel 5.15* and 5.14* fails to suspend

cn flag

As the title suggests, I cannot suspend my laptop using kernel 5.15.* or 5.14*. When trying to suspend, the screen goes blank but the keyboard backlight still lights up, and the fans are are on.

Laptop info

  • Asus ROG M16
  • 11th Gen Intel® Core™ i9-11900H @ 2.50GHz × 16
  • SK Hynix SSD
  • 1x 8GB and 1x 16GB Samsung DDR4 PC4-21300, 2666MHZ
  • Mesa Intel® UHD Graphics (TGL GT1)
  • Nvidia RTX 3060
  • Ubuntu 20.04.3 LTS
  • Kernel 5.15.2

Solutions tried

I have downgraded to kernel 5.13.19 and the suspend feature works again, but I cannot install nvidia-driver, either version 460 or 470. So I'm stuck between either having a working nvidia driver or a suspend feature.

I'm not sure how to provide the log when suspend fails but hope someone can guide me to debug this.

I also added a photo of my BIOS setting, in case the problem lies there.

I'm on a System76 Galago Pro running Pop!_OS 21.04 and suspend stopped working for me between in 5.13.0-7620 (works in 5.13.0-7614)

It seems that System76 cannot reproduce this problem on the same kernel version that I'm running which makes me think this may be specific to either NVMe or RAM (the only uncommon hardware components). What RAM and NVMe are you running? I'm running an ADATA SX8200NP and 2x 16GB Crucial 3200MHz.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
