Kernel 6.1 breaks PCIe / regression

VIM3
1

For some time I’m strugling to get my SATA controler to work with Manjaro’s kernel 6.x.
Everything worked with old linux-khadas kernel from 5.x branch, but after switch to linux-aml 6.x the PCIe devices is visible, but not initialized properly and no connected drives are detected.
This has been debuged in manjaro’s forum here: [VIM3] ASMedia SATA controller issues after replacing linux-khadas with linux-aml - #15 by zet - Technical Assistance - Manjaro Linux Forum

Without any results, I’ve gone with compiling the khadas 6.1 kernel (source from GitHub - khadas/linux at khadas-linux-6.1.y) and got same results: PCIe card controller is detected, but not initialized).

At first I thought that issues are with the SATA controller or ahci module used, but seems that it’s originating somewhere in meson-pcie.

So searching through this forum I’ve found that similar issue already have been reported before: Problem with meson-pcie patch

Latest dmesg output:

If more testing/logs are required just let me know. Hope we can fix that, as the 6.x kernel is already upstream in Manjaro.

Hello @zette

We will check this issue on our side.

I can recognize and load my SSD normally, I don’t have a SATA device with PCIe interface to test.

Please make sure your VIM3 is configured with PCIe instead of USB3.0.

I’m on PCIe mode, switching back to kernel 5.x, makes the controller working as usual.
In 6.x the controller is detected (visible in dmesg and lspci), but not fully initialized as ahci fails with -22 error.
