Raspberry Pi OS • Re: Raspberry Pi OS Lite (64-bit) - missing driver?

This has nothing to do with Lite vs Desktop.

The (literal) screen shot you provided shows that there are disk errors ("tag#16 uas_eh_abort_handler 0"). The driver (which is most definitely there) is doing the correct thing and reporting the errors.

And then "device offlined", due to the errors, which of course means that the boot code can't see the disk, so it drops into initramfs.

Best to take some wellness checks (fsck, etc) on the disk. If it were me, I'd be rebuilding the disk...at least.

Can I check if the sd driver in the Lite image is similar/identical to the sd driver in Full? Are there possible dependencies which could be missing?

It is built into the kernel and both releases use the same kernel.

These errors also appear if there are power issues.

@trejan I'm using the official 27W power supply. Why would Lite have power issues & Full would not? Consistently. But, will switch to another 27W psu tomorrow. But why would Lite have a power problem and Full would not?

Pass. Power issues are a common reason for errors and unusual behaviour. We get a lot of people who don't give full details on their setups so it is worth mentioning it.

What do you have plugged in? What is the power requirements for the SSD and the enclosure? You only have 1.6A in total across all USB ports and that is assuming you're using a compatible 27W PSU.

Those reset and abort handlers are a sign of fundamental USB implementation trouble. In the past, those handlers were not there or at least did not pop-up in logs or displays, just crash/freeze/lockup. It mostly means you bought a 'cable'/product with an incompatible/flaky USB-to-SATA or USB-to-NVMe chip inside. That happens when people want cheap and buy computers with no decent/modern/fast native storage I/O HW included. As already said, might be power issue as well (in addition), not the obvious visual when you measure with a multimeter or look at the specifications, but nasty short spikes/dips.
Also the Pi5 27W PSU is not the holy grail. I figured out yesterday that I need a certain sequence of plugging in connectors. If I unplug re-plug the way I usually do, it does not power-up my computer. Other old HP PSU or some newer white-label PSU work fine in that situation and also do clearly go beyond the basic 5V/3A. So It might also be that 5V/5A isn't enabled.

That the DE image does not fail might be a matter random luck or timing. My RPi4 could boot well, run stable for hours or days and then this USB stack crash still happened. My workaround was to setup the watchdog so it went on without service interruption. Finally I created an own power supply setup, also other ASMedia chip, the earlier one seemed to be to modern for the Pi4 at that time. Now I don't monitor/notice it anymore as most important software is moved to other ARM computer(s) that have M.2 NMVE slot onboard and run generic Linux Distro.
