** 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). The kernel starts running but then just stops:

It seems there's something different about some Pi 4s since the same
image boots just fine on other Pi 4s. I found that updating the Pi
firmware to at least 1.20201022 'fixes' the boot problem of these
'special' Pis.

Title:
[SRU] Pi 4B 2GB boot failure
Status in linux-firmware-raspi2 package in Ubuntu:
New
Status in linux-firmware-raspi2 source package in Bionic:
Fix Committed
Bug description:
[ 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). The kernel starts running but then just stops:

It seems there's something different about some Pi 4s since the same
image boots just fine on other Pi 4s. I found that updating the Pi
firmware to at least 1.20201022 'fixes' the boot problem of these
'special' Pis.
