Da scheint auf dem ROCKPro64 noch ein wenig Luft nach oben.

Ok, es gibt noch eine andere Möglichkeit.

Kamil hat mir noch ein wenig geholfen. Mit folgender Änderung werden die Platten gefunden.

hmm, I had to add /etc/default/extlinux: libahci.skip_host_reset=1

Sieht dann so aus.
# Configure timeout to choose the kernel # TIMEOUT="10" # Configure default kernel to boot: check all kernels in `/boot/extlinux/extlinux.conf` # DEFAULT="kernel-4.4.126-rockchip-ayufan-253" # Configure additional kernel configuration options APPEND="$APPEND root=LABEL=linux-root rootwait rootfstype=ext4 libahci.skip_host_reset=1"
Danach waren die Platten zu sehen.
root@rockpro64:/tmp/etc/default# blkid /dev/sda2: SEC_TYPE="msdos" LABEL_FATBOOT="boot-efi" LABEL="boot-efi" UUID="ABCD-FC7D" TYPE="vfat" PARTLABEL="boot_efi" PARTUUID="72e36967-4050-4bb3-8f8f-bf6755c38f28" /dev/sda3: LABEL="linux-boot" UUID="8e289a3e-0f9b-4da1-a147-51e03390637c" TYPE="ext4" PARTLABEL="linux_boot" PARTUUID="fe944fd2-3e42-4202-8a95-656e9bdb4be6" /dev/sda4: LABEL="linux-root" UUID="3e9513c6-dfd1-48c9-bee2-04bb5a153056" TYPE="ext4" PARTLABEL="linux_root" PARTUUID="d2d1dd88-030d-4f74-998f-7c9ce7d385d0" /dev/sdb2: SEC_TYPE="msdos" LABEL_FATBOOT="boot-efi" LABEL="boot-efi" UUID="56C9-F745" TYPE="vfat" PARTLABEL="boot_efi" PARTUUID="919c8f73-5f25-4a01-9072-3a5ed9a88ff2" /dev/sdb3: LABEL="linux-boot" UUID="23c19647-f4a1-4197-a877-f1bb03456bef" TYPE="ext4" PARTLABEL="linux_boot" PARTUUID="093d0cc0-d122-4dce-aeb5-4e266b4b7d9d" /dev/sdb4: LABEL="linux-root" UUID="f1c74331-8318-4ee8-a4f7-f0c169fb9944" TYPE="ext4" PARTLABEL="linux_root" PARTUUID="964ab457-58d5-40c4-bb02-dfd37bd2f0da" /dev/sda1: PARTLABEL="loader1" PARTUUID="37466429-e4a4-495c-b9a1-3f74625a3cae" /dev/sdb1: PARTLABEL="loader1" PARTUUID="33f692b3-54cb-4a37-b602-21a2baf32fa0"
Aber auch hiermit ist ein Boot von der SATA Platte nicht möglich.

Ich möchte hier noch was vom kamil zitieren.

(11:44:09) ayufanWithPM: will look later, but this controller is tricky, also on x86 as well
(11:44:16) ayufanWithPM: jms585 seems to be significantly more stable

Evt. bekommt er das gefixt 😉
