Description Marcela Maslanova 2024-03-13 10:32:01 UTC

With the latest kernel 6.7.7-1-default I'm getting this error message after giving my password for decryption.

hub 6-0:1.0: config failed, hub doesn't have any ports (err -19)

For the first time the boot failed and got into "maintenance mode". I tried to reboot to older kernel and that worked. After a few more reboots with the 6.7.7-1 it always show the message, but boot succesfully continued.

I found the similar error message on a user forum: https://askubuntu.com/questions/1463310/hub-8-01-0-config-failed-hub-doesnt-have-any-ports-err-19

Comment 1 Takashi Iwai 2024-03-13 14:34:08 UTC

I guess it's a spurious message seen at the boot for a USB 3.0 root hub.  It might be triggered by recent changes, but it should be harmless.

Tossed to Oliver, as a USB issue.

Comment 2 Oliver Neukum 2024-03-13 16:29:32 UTC

We need the extended registers for the XHC.
Please provide "lspci -vvv" for XHCI

Did you run this as root?

Comment 6 Marcela Maslanova 2024-03-14 10:01:31 UTC

I'm sorry. Now it's quite long, I attached it.

Comment 7 Takashi Iwai 2024-03-18 10:06:06 UTC

I guess this is really a dead / unused internal hub that has no port connected.
We may simply downgrade the error print to info?

IIRC, I have this in Lenovo T14s AMD Gen 3 model, which is also with Rembrandt.  The message isn't new, it's been present since over a year ago (don't remember any version it didn't show up).

Meanwhile P14s AMD Gen 4 doesn't seem hitting it.
