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

Gathering more evidence in support of a faulty motherboard theory. At some point I got this (system wasn't under heavy load - just a browser opened + remote video playback): https://gist.github.com/dshcherb/06f4e4a0260b6d5313df1594d959849a#file- nvme-failure-razer-dmesg-log-L2073 сен 10

Sorry, I should have mentioned that before: in the original test I also had a device plugged in via usb type-c (thunderbolt 3) - that device had an ethernet interface which you can see in the logs. It's another problem that I need to debug because type-c hot-plug of that device worked once but

I will try 2 things: 1. re-seat the card 2. get a card from a different manufacturer and test. It might be a buggy slot in the motherboard and if the problem persists with a new card I will know for sure that the slot is defective. -- You received this bug notification because you are a

This is the most heavily loaded configuration I use with this device and I don't have issues with either an NVMe SSD or GPU. No hardware-related issues with any USB devices (data goes through PCIe in the end). ➜ ~ lspci -v -t -[:00]-+-00.0 Intel Corporation Device 5910

I did get a lot of corrected PCIe errors previously which is why I set pcie_aspm=off (otherwise it flooded my kernel log instantly) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1687714 https://launchpadlibrarian.net/318000853/dmesg_pcie_aspm_rc8.log I need to think of a good test for

Seems like it's a PCI bus issue? Tons of errors happened before the ath10k_pci errors: мар 07 01:54:20 hostname kernel: ax88179_178a 4-1.1:1.0 enx00056b006ad7: Failed to read reg index 0x0002: -19 мар 07 01:54:20 hostname kernel: ax88179_178a 4-1.1:1.0 enx00056b006ad7: Failed to write reg index

I don't have a special wireless off/on button on my keyboard but I'm assuming rfkill will do (soft kill switch). The issue does not get triggered by the following loop (I may leave it for several hours to get a better picture and modify to wait more intelligently): ➜ ~ while

Seems like the PCI device no longer responds, so there are lots of -ETIMEDOUT. Does same thing happen when you press the wireless on/off hotkey? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670706
