Hi,
This is my first bug report on kernel, first crossposted here
(https://www.reddit.com/r/NixOS/comments/omctp3/rpi4_nixos_native_2105_and_ssd_by_usb3/)
and here on nixos github (https://github.com/NixOS/nixpkgs/issues/130499) :
[1.] One line summary of the problem:
Using an usb sata adaptater from Startech (USB312SAT3CB 3.1 firmware
upgraded) on my RPI4B 8gb with the kernel 5.13.4, during any dd=/
operation on SSD on USB 3 port, my systemd logs finish full of errors of
type :

buffer is full (sz: 512 bytes), total 32768 (slots), used 32768 (slots)
and

[2.] Full description of the problem/report:
I boot from a SD with nixos on RPI4B 8gb (firmware full upgraded to
latest), and try to configure/format/erase an external SSD
(CT1000MX500SSD1)
Because my startech adapter (USB312SAT3CB 3.1 firmware upgraded) not
working with UAS i use some kernel quirks to boot and go back on
usb-storage for the SSD.
The linked explanation for common RPI4/UAS/Sata adapters problems is
here :
https://jamesachambers.com/new-raspberry-pi-4-bootloader-usb-network-boot-guide/
> "usb-storage.quirks=174c:55aa:u"
> "usbcore.quirks=174c:55aa:u"
I use this dd command to write zero on disk for a future encrypted system :
dd if=/dev/zero of=/dev/mapper/ecrypt bs=1M status=progress
During the first ~70Go, i have no problem, but after that errors when
they appears accumulate quickly and fill all into my system journal (4gb).
The dd command never pass after 170 Go, system crash, and i have a 1To
SSD disk ...
Errors displayed in systemd already copy/pasted above.

Your problem is in the sdhci code, not the usb controller.
But even with this, does the operation succeed properly?
The rpi hardware is HORRID when it comes to the USB controller, so those
xhci messages might just be normal given the lack of irq handling that
the platform was known to have in the past (note, might be better now,
no idea, sorry.)
But again, is the operation failing? Is your sd card working properly?
Does the problem go away with a new/better sd card?
thanks,
greg k-h

Nop, operation failed, my systemd journal is full of these errors, 4gb
at the end,
and finally the dd command and system freeze at less than 15% of the dd
operation.

The sd is fresh new but, i could will try with another if the problem is
linked to sd.
My final objective was to use boot on SSD feature and not a slow SD for
my NIxos system support on RPI, so i suppose i could put this problem
aside, and prepare my SSD with another computer..
