[apm821xx] Test report of Attended Sysupgrade on my Meraki MX60

Hirsupp · January 19, 2026, 2:43pm

Recently I wanted to test the Attended Sysupgrade for the ongoing 25.12 release, so I performed it on my Meraki MX60. The new image of OpenWRT 25.12.0-rc2 seemed built well, but the boot of the new OS seemed failed. During the recovery of the old OS via u-boot, I noticed that the kernel image seemed successfully decompressed, but the linux kernel seemed not launched, and the system seemed to just hang there, but maybe it just needs more time to launch, as I was in a hurry with no patience to wait longer, at that time.

Is there anyone having tested OpenWRT 25.12.0-rc2 on Meraki MX60 or other supported apm821xx platforms?

### Describe the bug Recently I wanted to test the Attended Sysupgrade for the …ongoing 25.12 release, so I performed it on my Meraki MX60. The new image of OpenWRT 25.12.0-rc2 seemed built well, but the boot of the new OS seemed failed. During the recovery of the old OS via u-boot, I noticed that the kernel image seemed successfully decompressed, but the linux kernel seemed not launched, and the system seemed to just hang there, but maybe it just needs more time to launch, as I was in a hurry with no patience to wait longer, at that time. ### OpenWrt version 25.12.0-rc2 ### OpenWrt release 25.12.0-rc2 ### OpenWrt target/subtarget apm821xx ### Device Meraki MX60/MX60W Security Appliance ### Image kind Official downloaded image ### Steps to reproduce `owut upgrade --verbose --version-to 25.12` from 24.10.5. ### Actual behaviour System hanged with LED amber:fault on. ### Expected behaviour System boots with all selected packages in read-only volume, and configs inherited. ### Additional info Serial console suggested that the system hanged when u-boot launching the linux kernel, the kernel image seemed successfully decompressed, but the linux kernel seemed not launched. ### Diffconfig ```text ``` ### Terms - [x] I am reporting an issue for OpenWrt, not an unsupported fork.
