Kai-Heng, Am able to see "xHCI host controller not responding, assume dead" pretty much regularly during suspend/resume.
I verified that the kernel am using has patches mentioned in https://patchwork.ozlabs.org/project/ubuntu-kernel/list/?series=53395 and am using amd platform. I also have iommu disabled. Impact being system hangs for a while, watchdog kicks in and reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763594 Title: xhci hangs; reset results in NULL pointer dereference To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1763594/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
