Hello all,
I upgraded my Raspberry Pi 3B+ from 22.04 to 23.10.
The storage device where the OS resides is a USB hdd.
It is connected to the Pi via a ASMedia Technology Inc. X820.
After the upgrade to 23.10, Ubuntu crashes during boot.
To eliminate the X820 as a variable:
- I created a Ubuntu server 23.10 directly on a USB stick -> The pi doesn't boot
- I created a Ubuntu server 23.04 the same way -> the pi boots
After investigation, I found that if I copy the /boot/firmware folder from an old 22.04 image and replace the content of the Fat32 boot partition of the HDD with its content, Ubuntu boots again.
From the error I get during boot time, it looks like after booting, the USB HDD is not found or the root partition is not mounted properly.
Booting with an SD card and mounting the HDD, I see that no logs in /var/log folder are being updated
What should be my next step to get proper error messages and investigate further?
Thanks in advance,
Aurélien |
[Impact]
Boot from USB on Pi 3B+ doesn't work. When the onboard-usb-hub module is loaded, all attached devices are reconnected which is fatal if one of them is the boot device.
[Fix]
Revert the commit that added support for the hub on the Pi 3B+. This driver is no really needed for the Pi.
[Test Case]
See below.
[Regression Potential]
Other attached devices that contain the same hub and require the driver will no longer function properly. IMO that's a very unlikely scenario.
