1 month ago This appears to no longer be an issue on 6.8.7. Thank you for confirming that it was not affecting the normal surface kernel, Tibladar.
S0ix seems to be broken for me with linux-surface kernel 6.7. I was able to reproduce this across several reboots, with both kernels, with and without the dGPU kernel modules loaded.
I've configured systemd to unload the mwifiex_pcie and mwifiex modules before sleep, which seems to have worked for months until the 6.7 kernel.
I don't see any major differences between the two dmesg outputs, so I'm posting this partially to see if anyone else can reproduce this with 6.7, since I don't have any leads on what could cause this.
Environment
linux-surface hash (kernel 6.6): c58cae4193e8007cb1d8a548db759bcdc3ce5c24

Verifying sleep reaches S0ix:
After suspending (
systemctl suspend) and resuming (lid close+open), you can run the following:If your system is reaching S0ix, you should have non-zero numbers for the following two lines:
