There is no BIOS or such there, I couldn't find nothing like a serial number using lshw/hwinfo. On the boards themselves there some numbers.
Both boards are Rev 10.020200807, however another numbers I found on them differ, on the old one there is a E257384 2034, on the newer one E257384 2214.
Go figure out. From HK didn't get any clear answer, even if people there in the forum seam nice and helpful.
As for what you wonder about: don't think so, I might be wrong, though 🙂
Running a home NAS using Armbian/meson bullseye and openmediavault.
After apt upgrade today, my SATA disks are no longer spinning up or showing up in "fdisk -l". The system is on an SD card and still boots fine.
This is what I'm seeing:
[ 2.270633] scsi host0: ahci
[ 2.272861] scsi host1: ahci
[ 2.273074] ata1: SATA max UDMA/133 abar m512@0xfc700000 port 0xfc700100 irq 27
[ 2.273090] ata2: SATA max UDMA/133 abar m512@0xfc700000 port 0xfc700180 irq 27
...
[ 2.584971] ata1: SATA link down (SStatus 0 SControl 300)
[ 2.896948] ata2: SATA link down (SStatus 0 SControl 300)
Both disks work fine in another system.
I have tried to upgrade the firmware, no change. Moved to nightly and booted into linux-image-edge-meson64 (6.1.0), same issue.
Next, I tried booting into kernel 5.19.17-meson64, but the problem persists. I wonder what has happened here? Could it be a userspace problem (since I didn't downgrade userspace here, only the kernel)?
Any hints very much welcome!
