I have the same issue with Linux Mint 19 (Ubuntu 18.04 based) using kernel 4.15 but for QCA9377 chipset.
I compiled the 4.18 kernel using `make localmodconfig` and have the same problem. I had sources for kernel version 4.9.24 and it exhibits the same behavior (failed to wake target for write32) after going to suspend and then turning back on. Computer is a Dell Inspiron 14 3473. I've tried numerous debug steps like restarting network-manager, removing mac80211 cfg80211 ath10k ath10k_core and ath10k_pci modules then reinserting them and then restarting network-manager with no improvement. I have not played with "Wake on Wireless" settings yet (https://wireless.wiki.kernel.org/en/users/documentation/wowlan) While I have the QCA9377 I do believe this post is quite relavant: https://patchwork.kernel.org/patch/7548331/ so I'm going to check if that patch works for the QCA9377 and report back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670706 Title: Kernel Call Trace After Disabling an ath10k Wireless Device (Atheros QCA6174 802.11ac (rev 32)) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1670706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
