My previous v5.9 kernel runs pretty fine on that board, and can boot from root on LVM on NVME device without any problem. But for v5.10-rc2 kernel, the root complex just refuses to initialize. Although the rockchip pcie seems to be detected, but no PCIE bus added at all. Also tried to add CONFIG_PCI_DEBUG, but still no pci related dmesg except the rockchip pcie controller trying to initialize. Manjaro ARM's linux-rc kernel has the same problem too, so it doesn't seem to be a bug in my kernel config. For the dmesg extracted from initramfs: https://gist.github.com/adam900710/0415c1f19c07f65f892eeb848fd8dfbe Is there any known bug related to pci to cause such problem? Thanks, Qu
