Hi Leonardo,

Since v5.13-rc1 my NanoPI M4 (arm64 with pcie-attached nvme) does not boot any more.

I could bisect it down to your commit 9d57e61bf72336e13e4cd3c31e93ab26266296a8, just
reverting it from v5.13-rc6 makes the boot happen again.

The .dts file I use is arch/arm64/boot/dts/rockchip/rk3399-nanopi-m4v2.dts.

This is the output of lspci -vv:

Is there anything I can do to help you understanding why this is happening?

I apologize for not having bisected it earlier.

Kind regards,
Domenico
