Just ran into this bug just now on a Gigabyte Z790 UD AC motherboard. xhci_hcd WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state
Added kernel command line intel_iommu=off option seemingly helped slightly with improved boot times (usb slow initialization), however subsequently locked-up the BIOS/EFI with me manually setting bad memory SPD timings, reluctantly resetting CMOS via shorting using a screwdriver. After re-configuring the BIOS to sane OEM stable settings (eg. Deactivate overclocking Turbo Modes), xhci_hcd the error is now gone! (eg. dmesg |grep fail) This xhci_hcd error seemed to mysteriously occur after activating XMP. I've activated XMP in the past without problems, but XMP was only activated briefly alongside CPU Turbo mode. Weird! I'm really really not liking EFI/UEFI. Too many mysterious bugs popping-up. For those still monitoring, try hard resetting your CMOS (with the screwdriver/short pins) and then loading BIOS/EFI default settings. Shrugs as to whether XMP or CPU Turbo modes have any affect. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
