Booting my raspberry pi image hangs at some point. Where exactly?
I can netboot my Raspberry Pi 4 still fine, but when I flash the image onto a usb drive using wic, booting fails. I just stops to boot at one point. I'd be glad if someone could tell me where it's hanging so I could try to start tracking it down at the right place. All metalayers are on dunfell but not at the newest commit.
USB booting was working fine months ago and I don't really know at which point it stopped working.
This is the last I get from the serial console:

The rest sadly appears on the screen only, so here is an actual screenshot:
It seems to detect the usb drive just fine. The last related log line I get is
sd 0:0:0:0: [sda] Attached SCSI removable disk
Whatever is running (the kernel?) is not dead, though. Around 30 seconds later it prints a "vcc-sd: disabling" and some minutes later a "random: crng init done" (= random number generator is initialized).
Does anyone have an idea? I'll try to get my hands on an sd card in the meantime.
