Please provide your PCI host controller by 'lspci -tv'. And, I wonder if user space tool 'lspci' can dump whole PCI configuration space on your platform, so please provide full dump by 'sudo lspci -s xx:yy.zz -xxxx' (you can get the device number followed '-s' by 'lspci', and copy the number, like) 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b852 After kernel 5.18, we change to use standard pci API to read/write configuration space, so if possible please downgrade to 5.17 to see if that version works to you. Ping-Ke
