Research direction
Start by reproducing the reported regression on the Raspberry Pi 5 with the Pimoroni NVMe Base, comparing lsblk under the listed 6.1.61, 6.1.70, and 6.6.x kernels. Review the linked Arch Linux ARM forum discussion and collect kernel logs, since the issue provides no source file or test entry point. Done means the NVMe SSD is detected on the affected 6.6.x kernels or the regression is narrowed to a documented kernel change.

Description
Describe the bug
Connecting an NVMe SSD using the Pimoroni "NVMe Base for Raspberry Pi 5" on Arch Linux ARM with kernel versions prior to 6.6.x not on versions 6.6.9 and higher.
Steps to reproduce the behaviour
Using Arch Linux (in my case AstroArch) with connected a PCIe extension board with NVMe SSD connected.
- Boot from release 1.7 with kernel 6.1.61-1-rpi-ARCH
- with command
lsblkI can see the SSD - update the system with update-astroarch with kernel 6.6.12-1-rpi and reboot
- with command
lsblkI can’t see the SSD - downgrade the kernel with
sudo pacman -U https://alaa.ad24.cz/packages/l/linux-rpi/linux-rpi-6.1.70-1-aarch64.pkg.tar.xzand reboot - with command
lsblkI can see the SSD

System
OS: Arch Linux ARM aarch64
Host: Raspberry Pi 5 Model B Rev 1.0

Logs
No response
Additional context
I’ve tried with different kernels and with kernels after 6.6.x (linux-rpi-16k too) can’t see the SSD.
Asking on Arch Linux ARM forum don’t seems to be a modules issue.
