There is additional platform context in the recovered kernel journal: repeated PCIe AER Correctable Data Link Layer errors (BadTLP/BadDLLP and one Timeout) on NVMe device 10000:e1:00.0 occurred throughout the boot and clustered at 19:17–19:19 shortly before the xHCI Host System Error. I am not claiming those AER events caused the xHCI failure, but they may be useful when considering a broader PCIe/IOMMU/platform/firmware issue.
System details relevant to the recovered log: - Ubuntu 26.04 - kernel 7.0.0-29-generic, Ubuntu 7.0.0-29.29-generic (upstream 7.0.12) - Intel xHCI 0000:00:14.0, PCI ID 8086:7a60 - ASUS ROG Strix G18 G814JVR - BIOS G814JVR.320 dated 2024-10-24 - NVIDIA driver 580.173.02 I am attaching a compact kernel evidence extract containing the Xid events, PCIe AER sequence, xHCI/DMAR failure, UCSI errors, and manual xHCI recovery trace. ** Attachment added: "fafnir-launchpad-2163551-kernel-evidence-20260814.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163551/+attachment/5992286/+files/fafnir-launchpad-2163551-kernel-evidence-20260814.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163551 Title: Intel Raptor Lake xHCI stalls with stale USB devices; USB input and external display freeze, i8042 keyboard also stops responding To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163551/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
