Raspberry Pi 4b not booting after update

Postby nhasian » Fri Mar 25, 2022 10:49 pm

Had everything up and running nicely with my Raspberry Pi 4b. I ran pacman -Syu and it updated the following packages:
raspberrypi-bootloader-202203
linux-rpi-5.15.30-2

During the update it got to 80% of linux-rpi and then hung. Now I am unable to boot. Any suggestions would be appreciated. pic attached of what is displayed when trying to boot.

I had this problem too. It has to do with viewtopic.php?f=65&t=15953. A freeze resulting from a bug in a usb3 hub driver. In combination with vfat your system freezes..
I don't remember exactly how I fixed it. But I have mounted the usb disk with boot/root partition on my laptop and restored the boot directory from the package cache. (think of the linux-rpi kernel files and raspberry bootloader and firmware).

good luck!

Yes, upstream bug. See the fix in the thread idovitz linked. Once you have the latest kernel installed, updates should be fine moving forward.

Hi all,

I think I've been biten by the same bug. rpi 4b 8Gb.

I was booting from an external usb3 ssd connected directly to the rpi without problems, but after some point (don't know exactly when) with kernels 5.15.30-x-rpi-ARCH the boot process stops with errors related to the disk.

Currently I'm using kernel 5.15.30-4-rpi-ARCH.
I think my last ok boot was with 5.15.30-1-rpi-ARCH because with 5.15.30-2-rpi-ARCH it began to show problems.

If I unplug this ssd from the usb3 port and plug it into the usb2.0 the boot process and posterior usage works flawlessly.

Any ideas about what can be done?

Thanks!
