Research direction

Start by reproducing the failure with the Pi 4 booting from a USB3 SSD, then attach a second USB3 HDD and compare it with USB2 and SD-card boot scenarios. Collect kernel logs before they become unavailable and use the reported hardware, firmware, and kernel versions to identify the affected USB-storage path; done means a reproducible cause and a verified kernel fix.

Written by the indexing model from the issue text.

Description

I use the Pi4 booting with a USB3 connected SSD.
This works nicely, but when I connect in addition an external USB3 HDD to the USB3 port, then the system crashes with "IO errors". Any commands like "dmesg" are not available any longer.
Connection of the HDD to USB2 port works. Booting from SD card and connecting the USB3 SSD and the USB3 HDD at the same time works.

Actual behaviour
The GUI disappears (only background is visible). Some "IO errors" are indicated.
