Getting this xhci_hcd fail or slow boot more so down to the cause, I've been debugging enabling power-on via keyboard/mouse, and again this xhci_hcd fail showed-up after, not when enabling ErP setting (below power-on via keyboard/mouse settings), but merrily toggling the ErP enable/disable option within BIOS/EFI screen and then rebooting/power cycling. ErP (Energy-Related Products) mode is somewhat directly related with powering on via keyboard/mouse. What's exactly transpiring here I do not know, as BIOS/EFI settings tend to be elusive, especially when the settings modify other values on another BIOS/EFI screen or settings not displayed.
Likely a PCI(E), in this case an xhci_hcd (USB bus) device, is having problems waking after power-off due to either ASPM/ErP? If this is the case recommendations else where suggest disabling ASPM and/or ErP. NOTE: Fast/Ultra-fast boot BIOS/EFI settings also provides further refinement for waking via keyboard/mouse, so some settings might be intermingling with ErP, and maybe ASPM. Since BIOS/EFI documentation nowadays (in my case Gigabyte) is significantly increasingly lacking, can only guess based on how the PC boots? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749961 Title: xhci_hcd: TRB DMA errors reported with ASMedia ASM1142 USB 3.1 Controller To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1749961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
