Bug ID: 216428 Summary: Thunderbolt 4 PCI Bridge Fails to Receive Proper PCI Resources Product: ACPI Version: 2.5 Kernel Version: 5.19.5 Hardware: AMD OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: BIOS Assignee: acpi_b...@kernel-bugs.osdl.org Reporter: babakre...@gmail.com Regression: No Created attachment 301701 --> https://bugzilla.kernel.org/attachment.cgi?id=301701&action=edit dmesg output without TH4 card Device Info: Motherboard : MSI MEG-X570 Godlike (MS-7C34) Processor : Ryzen 9 5950x Graphics: Radeon VII ( Vega 20 ) Thunderbolt : Asus ThunderboltEx 4 (Maple Ridge 4C 2020) kernel cmdline : pcie_ports=native pci=assign-busses,hpbussize=0x33,realloc,hpmmiosize=128M,hpmmioprefsize=16G Problem Description: I am attempting to enable the TB4 card on my system and have discovered some issues that prevent me from initialize the card and plug in a eGPU. However, I am unable to set kernel parameters that result in a successful boot. When I have no kernel command-line parameters, I have a successful boot but no BAR address space to support ePGU plugin. With command-line parameters set, I have boot failure and a initramfs ( rootfs ) prompt, there seems to be misconfiguration of PCIe, neither the SATA or NVMe controller show up in dmesg. -- You may reply to this email to add a comment.
