After investigation, I think I’m the victim of two bugs:

• the first is the one described here:

Since kernel 6.6.8, I’ve been having suspend issues. Sometimes, a suspend request would result in the screen blanking, but the power LED remains lit. Other times, suspend would occur, but randomly, the system wakes itself (power LED is solid white), and eventually the fans turn on to full speed and the system gets very warm. A long press of the power button shuts it down, and it reboots normally. After a bit of experimenting, the bad suspend only occurs on lid close. Suspend works normally if a suspend is requested by pressing the power button. This behaviour has been confirmed by other Asus G14GA402 users, as well one Asus TUF Gaming A16 Advantage Edition FA617NS user. There was no issue with suspend on kernel 6.6.7 and lower. The issue has persisted through 6.6.8/9/11/13 and 6.7.2.

The kernel 6.6.8 was released in “stable” on 2023-12-25, I think that’s when I started having problems that I considered random.

• Then I encountered this second bug, which is totally reproducible.

Summary of QCNFA765 ath11k problems kernel-6.7.4

The current 6.7.x suspend crashes are intertwined with the long standing packet loss and latency problems we’ve been seeing with QCNFA765 Linux ath11k.

Kernel 6.4.12-6.6.14 all had the same problem where you need the iw dev wlp1s0 set power_save off workaround to prevent crippling packet losses and slow speeds. With the power_save workaround applied this wifi adapter was mostly tolerable.

Kernel-6.7.3 broke suspend.

Kernel-6.7.4 included a partial fix.

I think I have this issue since 2024-02-06 when this was published in stable.
