Raspberry Pi 4 doesnt boot after apt full-upgrade

[melqui]

Raspberry Pi 4 v1.2 4GB

Steps to reproduce bug:

1. Install latest image 32bits recommended from Pi imager 1.3 , from zero.
2. run sudo apt update && sudo apt full-upgrade -y

Result intermmitent booting.

Official power supply, tested various sd cards, latest critical firmware (and latest stable too).

Bug dont occurs with original image (without update) or other distros and 64 bits.

I restored my 4B4 to the default "critical" firmware, and I can confirm this problem.

Starting with a freshly written card (RaspiOS32 from Raspberry Pi Imager) I went through the Welcome to Raspberry Pi startup configuration script, and initially it rebooted fine. However attempting several more reboots resulted in a few boot failures.

The system seemed to shutdown fine, and my monitor would go to sleep then wake up again as it usually does when the system reboots, but then nothing. Monitor remained live as if it was receiving a signal, but there was no activity indicated by the ACT LED and nothing on the screen.

My USB-SSD booted 4B2 on the latest "stable" firmware rebooted fine (many times) after update/full-upgrade (RaspiOS32).

Gonna try the 4B4 card in that system... (will report back).

EDIT
Happens with the "stable" firmware as well. Not sure why it hasn't affected my SSD (as far as I can tell).

I'll see if enabling the serial console output shows anything interesting...

EDIT-2
Well that's unfortunate. It seems that enabling the serial console output fixes the issue. Rebooted a couple of dozen times with no failures. Disabled the serial console and got a boot failure after a few reboots. So nothing interesting to capture and post (I hate this intermittent stuff). But at least it explains why my SSD wasn't encountering this problem.

I did capture output from the bootloader itself, and it shows nothing interesting (successful and failed boot outputs are identical).

Looks like bug in kernel. I had to reconfigure all my software and stay in original image, without apt upgrade. Please, someone let me know when i can update system again!

[melqui]

Any update for solve this?

How to downgrade to latest 4.19 kernel?

I am also having the same problem. Everything was since Feb 2020. Just a few days ago another update - I do it at 8PM every day. When booting it's just a blank screen.

Fortunately I have a second SD card which I use as backup and this one runs fine.

The boot eventually does seem to work, but after 3-4 power-off/power-on attempts.

Richard

Critical bug!

Critical bug!

Not so sure about that...

I have tried to reproduce the problem again, starting over with a freshly imaged card, and I have not been successful.

Only difference was the first time I used a 16GB card and this time it was 32GB. So I re-wrote the exact same 16GB card I used the first time, and it's working fine now ...

As far as I can tell, anyway. I've lost count of how many dozen successful reboots and power off/on restarts I've had. But with this intermittent stuff ...

Did I mention that I hate this intermittent stuff.

I tested with a 16GB SanDisk Ultra and 32GB Kingston Canvas Select

I grabbed an old SD Card and created a bootable RaspiOS ARMHF with Pi-Imager, booted no issues, configured, rebooted, fully updated, rebooted, eeprom to stable, rebooted, rebooted, rebooted.

If you see an intermittent issue please can you post 'vcgencmd version' and 'uname -a' here on the occasions where it does boot so that we can more accurately track versions with intermittent issues.

Other information which might be relevant is the display(s) resolution and any overclocking settings in config.txt because these change clock speeds.

The most stable Raspberry Pi OS nightly is 2020-08-12 available here http://downloads.raspberrypi.org/nightlies/ for test purposes so it would be good to know if that fails. I'm guessing you have the same firmware and kernel as the newer 2020-08-18 image.

If i do sudo rpi-update 866751bfd023e72bd96a8225cf567e03c334ecc4 , OK again.

Latest Kernel (https://github.com/Hexxeh/rpi-firmware/ ... 506a1ebeb9) don't solve, intermittent booting.

Might be related: I also noticed intermittent boot issues with the latest rpi-update firmwarre when testing on LibreELEC.

I didn't get anything from earlycon but adding uart_2ndstage=1 showed some interesting things: loaded kernel.img size was 0x0 and I got a bunch of "SDCARD_CONTROL_POWER"/"SDCARD_CONTROL_WRITE_PROTECTED" not defined lines from the firmware.

Sometimes cold-boot (power unplugged) failed, sometimes reboot failed, most of the time boot works.

Thanks @HiassofT that's very useful

BTW: earliest firmware with intermittent boot issues so far seems to be Jul 31 which failed to boot on second try - haven't noticed anything unusual yet on Jul 17 and before.

If i run sudo rpi-update 866751bfd023e72bd96a8225cf567e03c334ecc4 (latest 4.19), i can upgrade to a new fixed kernel in future simply run sudo apt update and full-upgrade ?

or better

Can I

sudo apt-mark hold raspberrypi-kernel

and

sudo apt-mark hold raspberrypi-bootloader

For maintain the 4.19 kernel and do all other upgrades normally, without issues?

I was able to reproduce something with similar symptoms but only with one board + SD combination. Which board(s) / SD(s) failed for you?

Would you be able to try this experimental firmware fix?

Testing is looking good so far, RPi survived about 30 reboots. I'll keep an eye on it and see if I can make it fail.

It's a fix for an occasional failure to boot (kernel.img not found). Yes, a future apt upgrade of the firmware will work fine.

There's a firmware tweak for a subtle timing issue in the FW SD driver. You can copy the files to /boot but don't do this on a card which contains important data because you are probably only the third person to test this

It might be better to wait for the APT update

At moment, my pi4 is in factory image (2020-05-27) without update/upgrade

If I run

sudo apt-mark hold raspberrypi-bootloader

and upgrade kernel and all other packages, will prevent this issue?
