oops message

I noticed my laptop is not able to boot into graphic mode today and kernel oops is logged to console.

This problem reproduces randomly and blacklisting ucsi_acpi fixes the problem. When it reproduces, a device `ucsi-source-psy-USBC000:002` is shown in `/sys/class/power_supply` with type `Unknown`.

Hardware:

* ThinkPad p15 gen2
* Dell TB16 thunderbolt 3 docking station
* AC power adapter

Kernel: 5.19.0-1-default

Comment 1 Takashi Iwai 2022-08-17 11:31:06 UTC

Could you give the hwinfo and dmesg outputs taken before the disconnection, as well as the dmesg after the disconnection?
