https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237666 bawdyanarchist@disroot.org <bawdyanarchist@disroot.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bawdyanarchist@disroot.org --- Comment #127 from bawdyanarchist@disroot.org <bawdyanarchist@disroot.org> --- Hi, I want to report having duplicated this exact same error on BHYVE virtual machine with PCI passthrough for the USB. HARDWARE: TRX40 Tachi with Ryzen 3960x (amd64) HOST SYSTEM: 12.1-RELEASE-p8 BHYVE Versions tried: 11.4-RELEASE, 12.1-RELEASE, 12.1-STABLE, 13.0-CURRENT BEHAVIOR: Without PCI passthrough, the host xhci controller operates normally with no errors. After rebooting host, the bhyve VM can be started, only once, with no USB xhci errors. However, if the VM is power cycled without cycling the host, I get the same sequence of errors reported by Mark, in a continuous loop, and inserted USB devices are undetected. Although the screen is impractical to use due to error messages, it is possible to login. I can SSH into the VM and otherwise use it normally. After 3-5 minutes, the loop stops, the VM detects devices, and I can access them. SPECULATION Problems with PCI reset? Perhaps my hardware doesn't support reset or re-initialization of the device without reseting all devices? -- You are receiving this mail because: You are the assignee for the bug.home | help
