Source: linux
Version: 6.12.6-1
Severity: normal
X-Debbugs-Cc: forestix@nom.one

Dear Maintainer,

After upgrading from the 6.6.x kernel to the 6.11 series, fastboot (the
tool for communicating with Android bootloaders) fails to perform
various operations over USB.

I use fastboot to install kernels on LineageOS phones. Without it, I am
no longer able to apply security updates to these devices.
The problem also manifests with simpler operations like reading a
variable from the bootloader. For example:

  fastboot getvar kernel

A typical error message when the failure occurs:

  getvar:kernel  FAILED (remote: 'GetVar Variable Not found')

I can reproduce this at will. It happens about 50% of the time when I
run the above getvar command, and almost all the time when I try to push
a new kernel to the device.

This is an upstream bug. I have not yet reported it upstream, but I
intend to once I figure out whom to include in the email. (If someone
here knows the best upstream lists & individual contacts to include,
please tell me.)

Git bisect reveals this as the offending commit:
63a1f8454962a64746a59441687dc2401290326c
xhci: stored cached port capability values in one place
