Source: linux Version: 6.12.6-1 Severity: normal X-Debbugs-Cc: fores...@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 -- System Information: Debian Release: 12.8 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable'), (1, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 6.12.6-amd64 (SMP w/32 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
