Under arm64-aarch64-RPI3-20201105 on RPi4, I am seeing the following messages in the logs:

Got these messages too under freebsd 13.1-release on raspberry 4b.

Same bug:

Comment 3 Please 2023-06-01 08:05:38 UTC 
also on freebsd 13.2
Comment 4 Max Stucchi 2026-02-10 13:01:37 UTC 
I am seeing these messages on a 15.0-RELEASE system.  Effectively, on a CM4, it means that no USB port on the board (I am using a 52PI CM4 router board - https://wiki.52pi.com/index.php/EP-0146) works.

I have tried tweaking config.txt in different ways, but to no change.

I would be happy to provide access to the board if needed for additional debugging.

In what way is the SDHCI issue (suboptimal reaction to a failed command) related to any USB problem?
Comment 6 Max Stucchi 2026-03-03 06:39:00 UTC 
(In reply to Michal Meloun from comment #5)

Hi Michal,

in my case, no USB port is usable as it just does not get recognized.

I see, but this is truly unrelated to the above bug. The problem with the SDHCI driver cannot affect the USB in any way.
