[Bug 2146647] Re: ucsi_acpi USBC000:00: error -ETIMEOUT: PPM init failed

[Simon Johnsson]

Hey there Laska! Thanks for the bug report, and sorry to hear about the
issue.

This sounds to me as a firmware bug possibly related to the laptop's
embedded controller. I would as such refer you to either:

https://discourse.ubuntu.com/c/support-and-help/

or

https://askubuntu.com/

as this does not appear to be a package related bug.

All the best,
Simon

Title:
  ucsi_acpi USBC000:00: error -ETIMEOUT: PPM init failed

Status in rust-coreutils package in Ubuntu:
  Invalid

Bug description:
  Hello!
  I have several operating systems on my laptop. I installed Kubuntu 26.04 Beta and Kubuntu 25.10 to test them for myself. However, after changing the boot order in Buios/Uefi , both versions of the distributions would no longer boot, and would display an error:

  ucsi_acpi USBC000:00: error -ETIMEOUT: PPM init failed

  The error occurs after changing boot order in Bios. I have a Lenovo
  ThinkPad E16 Gen 3 laptop with USB charging and a connected USB mouse.

  I managed to reproduce this bug several times. The procedure is approximately as follows:
  1) Install Kubuntu 24.04 LTS or another stable distribution.
  2) Install Kubuntu 26.04 Beta or Kubuntu 25.10 on the disk next to it
  3) Go to Kubuntu 24.04 LTS, Kubuntu 26.04 Beta | Kubuntu 25.10 and check that everything works.
  4) Go to Bios and change the boot order. I put usb boot at the top of the list
  5) Connect LiveUSB to the laptop and turn on the laptop (PC). You don't need to install a new OS, just check that the boot order works correctly. Exit
  6) Unplug LiveUSB. Try to boot Kubuntu 24.04 LTS, Kubuntu 26.04 Beta | Kubuntu 25.10 . This step may reproduce the error
  7) If the previous step did not produce an error, then change the boot order in the bios again and the error will reproduce
