** Description changed: + [ Impact ] + + Boot failures are being observed with the current Bionic image in some + (but not all) Pi 4 2GB rev 1.4 boards (identified by revision code + b03114 in /proc/cpuinfo). The back-port is intended to rectify booting + on these machines. It is expected that most future 2GB boards in the + market are likely to be revision 1.4 as this is the latest revision of + the Pi 4 board. + + [ Test Case ] + + * Flash Ubuntu 18.04.5 preinstalled server arm64 image to an SD card + * Boot the card on a Raspberry Pi + - Please note that failure has only been observed (and only intermittently) on the Pi 4 2GB rev 1.4 boards + - These boards can be identified as having the Revision b03114 in /proc/cpuinfo + - On these boards, boot *may* fail during kernel startup with the current firmware. If it fails, boot the card on another Pi and ensure it completes successfully + - On all other boards, expect successful boot at this point + * Upgrade all packages: sudo apt update && sudo apt upgrade + * Enable proposed: https://wiki.ubuntu.com/Testing/EnableProposed + * Upgrade linux-firmware-raspi2 to -proposed version: sudo apt install -t bionic-proposed linux-firmware-raspi2 + * Reboot and ensure boot completes successfully on all Pi models + - Please note that if you switched the SD card to successfully boot previously (due to boot failure on a 2GB rev 1.4 board), remember to switch the card back to the original Pi to re-test boot and verify it completes successfully + + [ Regression Potential ] + + As with anything updating with the boot sequence, boot failure is a + possibility. However, the boot firmware being back-ported is currently + in active use on focal and hirsute with no issues, and the purpose of + the back-port is to fix an existing observed boot failure in the new + generation of Pi 4 2GB boards (which are now becoming more prevalent in + the market). + + [ Original Description ] + Some Pi 4B 2GBs fail to boot the current raspi bionic server image (and core18).
