Bug 1212365

The log tells us what is happening but not why. Is this on a Raspberry? The device is known to be quirky and initialization has been canged comparatively recently. Please also provide the output of "lspci -v"

lspci -v output

It's not raspberry pi, it's a pciex1 card that I've purchased

Please also provide te output of "lspci -vn"

lspci -vn

As this is a regression, the obvious culprit is
5255660b208aebfdb71d574f3952cf48392f4306 ("xhci: add quirk for host controllers that don't update endpoint DCS")

Revert the obvious suspect

I could create branch on obs and apply the patch to test it or do you want me to do it some other way?

Yes, it is fine to test this with a kernel generated in obs.

Obvious suspect is the correct one :) It works now. Now we need to detain the suspect!

OK, this needs to go upstream. Please provide the output of "lspci -vvvn" for meto include in the upstream changelog.

without pasting entire thing i think this is what you need

We got something from upstream:


Odd. There are many third party VLI cards in the field and this is the
first I've heard of an incompatibility.
Can you please report the output of
lspci -s 0b:00.0 -xxx
and pastebin a dmesg trace with xhci debug printks (and the quirk) turned on?

I'm on it but if you would like to help me with enabling the printk's i would be thankful

You can enable dynamic debugging on the kernel command line. In this case

dyndbg="module xhci_hcd +fpm"

(on the unfixed kernel) should do the job.

I was about to get the debug log but… I'm currently at 6.4.3 and it seems to be working just fine. 6.3.8 was the one with the fix, so maybe something changed between 6.3 and 6.4. And indeed I booted 6.3.9 (without fix) and it indeed doesn't work.
