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?
