Confirm that a fresh install of Armbian_21.08.3_Bananapipro_focal_current_5.10.60 does not get a visible sata connection (BananaPi Pro).
This cmd line followed by a reboot enables the sata (same is in first post, just all in one line).
apt install linux-image-current-sunxi=21.05.6 armbian-firmware=21.05.8 linux-dtb-current-sunxi=21.05.6

Hi again,
more findings:
It is sufficient to downgrade the device tree:
apt install linux-dtb-current-sunxi=21.05.6
I had compared the kernel config (find current config in /proc/config.gz), no changes regarding sata. Only a very few changes, mostly adding drivers as module.
So far I had no time to compare the device tree yet. Someone wrote he did that but did not find relevant changes. Well, I hope he was wrong :-).
BTW: the next line will reverse the changes.
apt full-upgrade
PS: Running a kernel with a different device tree is not recommend, I did it only to hunt down the issue a bit.

And more info:
Some people wrote that these events show up in the syslog and searched in that direction.
ahci-sunxi 1c18000.sata: supply ahci not found, using dummy regulator
ahci-sunxi 1c18000.sata: supply phy not found, using dummy regulator
ahci-sunxi 1c18000.sata: supply target not found, using dummy regulator
Since I was convinced these messages are normal, I double checked with working sata and they are there as well.

Decompiled the DT, then compared.
This is a difference regarding sata:
sata@1c18000 {
clocks = <0x02 0x31 0x02 0x7a>;
compatible = "allwinner,sun4i-a10-ahci";
interrupts = <0x00 0x38 0x04>;
phandle = <0x5f>;
reg = <0x1c18000 0x1000>;
status = "okay";
target-supply = <0x24>;
};
This line is new in latest version:
target-supply = <0x24>;
It is not unlikely that this line causes the issue.
The 0x24 points to item ahci-5v and that is disabled.
ahci-5v {
compatible = "regulator-fixed";
enable-active-high;
gpio = <0x19 0x01 0x08 0x00>;
phandle = <0x24>;
regulator-boot-on;
regulator-max-microvolt = <0x4c4b40>;
regulator-min-microvolt = <0x4c4b40>;
regulator-name = "ahci-5v";
status = "disabled";
};
No change for this item between the versions.
I do not know how to enable it (yet). Any ideas ?
This is how I extracted the DT and decompiled:
copy "/sys/firmware/devicetree" to my worksation
running "dtc --in-format fs base --out-format dts --out dt.dts --symbols --auto-alias --phandle both --sort"
use meld to compare both versions
