https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289943 Bug ID: 289943 Summary: Kernel hang on X11SCM-F in UEFI mode booting off nvme drive. Product: Base System Version: 13.5-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: bicknell@ufp.org FreeBSD 13.5-RELEASE on a SuperMicro X11SCM-F motherboard booting in UEFI mode off an nvme drive with as ZFS file system. Board is running the latest available BIOS from SuperMicro (2.7, 2025-04-02). System boots fine in Legacy mode, all hardware is recognized. The problem with Legacy mode is that it can't boot from an NVME drive, and the goal here is to migrate from some old SATA drives to some new NVME drives. Kernel loads and probes most of the hardware successfully. Hang occurs after probing pcbib6: pcib6: <ACPI PCI-PCI bridge> ira 19 at device 28.3 on pci0 pcib6: failed to allocate initial memory window: 0x90000000-0x910fffff Based on a lot of articles online I've tried the following: - Turning on/off fast boot. - Turning on/off C-states. - Turning on/off Above 4GB MMIO BIOS Assignment. - Appears to need to be on, or I don't even get this far. - NVMe Firmware Source in both "Vendor" and "AMI" mode. - Network Stack on/off. - Booting in verbose mode to get more information. I will also attach the /boot/loader.conf file in use, which works fine in Legacy mode, a dmesg.boot from Legacy mode, and an lspci output. -- You are receiving this mail because: You are the assignee for the bug.home | help
