Anyway, just to be clear, it always fails to suspend to RAM. I'll try with 4.9.7, should be in fedora stable for fedora 24 pretty soon. Same here. My laptop is an Acer Aspire V13 (aka. V3-371), with ath10k_pci/qca6174 for the WiFi. Closing the lid triggers suspend-to-RAM, which makes the WiFi firmware crash. Consequences: unresponsive WiFi hardware => frozen WPA-supplicant and frozen NetworkManager (not even kill -9 can kill the process); and power-off takes ages! Please find attached the output of `journalctl -b0`; problem starts at line 1562. Note however that the _first_ suspend seems to work, and the problem appears at the second suspend (look for regex “Lid [co]”): ``` firmware crashed!

`journalctl -b0` after ath10k_pci firmware crash on suspend on Acer Aspire V13
I can confirm this on 4.12 at least |
Created attachment 252811 [details] messages when attempting the suspend to ram with ath10k_pci loaded This is on Fedora 24. Updated from kernel 4.8.16 to 4.9.4 and now I can't suspend to ram anymore. When I attempt to suspend to RAM screen becomes black, but after a few seconds it comes back instead of suspending. I think the fault is in the ath10k driver because if I modprobe -r ath10k_pci and the attempt to suspend everything works as expected. Having ath10k_pci loaded prevents the suspend. Also in dmesg I can see the driver complaining the firmware crashed (see attachment for messages snippet). After the suspend to ram failed the OS is in a zombie state. Programs do not close correctly, the usually stay in defunct state, but do not move from there. I usually use SUB sysrqs to reboot at this point. Might be related: even when I simply modprobe -r ath10k_pci I get a firmware crash: [ 61.104169] ath10k_pci 0000:03:00.0: firmware crashed!
