Public bug reported: The armhf kernel on the current uc20 beta image (5.4.0-1011.11 r156) boots fine on rpi4, but when the system refreshes to 5.4.0-1011.15 r179, the system does not boot. After it gets to "Starting kernel..." it just stops. Attempting to power off/on the device after the failed boot fails in the uboot script: Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1...

This does not seem to happen with the arm64 kernel, and booting the armhf kernel seems to work fine on pi3 devices - it just seems to be the combination of armhf and rpi4 that breaks right now. ** Affects: snapd Importance: Undecided Status: New ** Affects: linux-raspi2 (Ubuntu) Importance: Undecided Status: New ** Tags: uc20 ** Tags added: uc20 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1888691 Title: [uc20] rpi4 does not boot with armhf on recent 5.4 kernel snaps Status in snapd: New Status in linux-raspi2 package in Ubuntu: New Bug description: The armhf kernel on the current uc20 beta image (5.4.0-1011.11 r156) boots fine on rpi4, but when the system refreshes to 5.4.0-1011.15 r179, the system does not boot.
