#78503 — Bug#1032948: linux-image-6.1.0-5-amd64: oops in ucsi_acpi_notify

Package: src:linux
Version: 6.1.12-1
Severity: important
X-Debbugs-Cc: jcristau@debian.org

Hi,

After upgrading to 6.1.12-1 my laptop started hanging regularly (3 times
in a few hours).  Downgraded to 6.1.8-1 and I've not seen this for a
week, so this looks like a recent regression.
Not all the hangs left traces in logs, but I got at least one oops:

Bummer.

Since 6.1.8 I found the following 2 commits in drivers/usb/typec/ucsi:

3d7f77e55da3455c8844b651e37779c90e201f48 titled
"usb: ucsi: Ensure connector delayed work items are flushed"

fdd11d7136fd070b3a74d6d8799d9eac28a57fc5 titled
"usb: typec: ucsi: Don't attempt to resume the ports before they exist"

Especially the first one looks 'promising'.
Can you make a patch which reverts that commit and use 'test-patches' from
https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html
to build a kernel and test that?

The following looks similar, though it is reported to happen on dock
unplug. I assume your issue is independent on that?

And if you do some bisection/tests with the above questions from
Diederik, might you try as well

https://patchwork.kernel.org/project/linux-usb/patch/20230306103359.6591-2-hdegoede@redhat.com/

(it is not yet applied mainline).

I guess that is https://bugzilla.kernel.org/show_bug.cgi?id=217106 ?

Not sure why patchwork still shows v2 of the patch as v4 is available here:
https://lore.kernel.org/all/20230308154244.722337-1-hdegoede@redhat.com/

Reverting "usb: ucsi: Ensure connector delayed work items are flushed"
doesn't fix the crash, pretty much instant upon unplugging my monitor.

I'll give the patch series you linked in the other reply a go now.

Thanks for letting me know.  I've built 6.1.22 from upstream and it
doesn't seem to crash.

That's awesome :-) Let's hope it stays that way now ;-)

You may have seen it on IRC already, but could you test a
Debian 6.1.20-1 kernel with (only) those patches applied?
These are the URLs:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.1.y&id=1c5abcb13491da8c049f20462189c12c753ba978
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.1.y&id=1e8525f37871741a52370627633962f8bdcab15a

If you need help with that, feel free to ask :-)

If we know that fixes the issue too, then we have the option of going for
a 6.1.20-2 release with just those 2 patches (and what's already in -2 now).

TIA,
  Diederik

Testing this now:

linux (6.1.20-1a~test) UNRELEASED; urgency=medium

  * Testing patches ../0001-usb-ucsi-Fix-NULL-pointer-deref-in-
    ucsi_connector_ch.patch ../0001-usb-ucsi_acpi-Increase-the-command-
    completion-timeou.patch

and it doesn't seem to crash, as far as I can tell.

Great, thanks! Then I'm going to pick those two commits as well for
6.1.20-2 and do that before continuing on 6.1.23.

#78694 — Bug#1032948:

Hi,

I'm also affected by this - recent lenovo laptop with a dock that
connects/removes multiple usb devices at the same time. Been getting
the oops after every resumption or every time multiple usb devices got
reset, with 6.1.0-6 and 6.1.0-7.

Built and booted a patched debian 6.1.20 and been using it for ~1hr
now without experiencing any issues. Connected and disconnected the
dock (and its devices) multiple times, suspended/resumed twice as
well.

I'd prefer to keep using it for some more time before calling it a
success, but it certainly feels better. With the normal kernel
disconnecting the dock was triggering a crash almost every time.

Still stable throughout the day with the patched kernel. No oopses or
crashes after unplugging the dock or random usb devices and
suspending/resuming multiple times since yesterday.

It seems these patches solve the issue - for my combination of devices at least!

best,
Costas
