https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291612 Bug ID: 291612 Summary: System hangs at ppt initialization with PCI‑USB controller on FreeBSD 14.3 Product: Base System Version: 14.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: Clockwork6400@protonmail.com After upgrading from FreeBSD 14.2 to 14.3, the system fails to boot when a PCI‑USB controller card is installed and configured for passthrough (ppt). Boot hangs at the moment of ppt initialization. * On 14.2 the same hardware worked fine. * On 14.3 the system hangs both in normal and single‑user mode. * Removing the PCI‑USB card allows the system to boot normally. Steps to Reproduce: 1. Install FreeBSD 14.3‑RELEASE. 2. Configure PCI‑USB controller for passthrough (pptdevs in /boot/loader.conf). 3. Boot system. 4. Observe hang during ppt initialization. Expected Result: System should boot successfully with PCI‑USB controller reserved for passthrough. Actual Result: System hangs at ppt initialization.
