Public bug reported: The latest Stonking 7.3 kernel and daily images contain this patch [0], which selects a clock rate that is incorrect on some variants of the Snapdragon X2 Elite platform (and potentially others using similar keyboards).
An upstream patch [1] has been submitted to the mailing list by a qcom engineer which fixes this issue on my platform and at least one other reported platform. A PPA build is ongoing here [2] (but I confirmed with a local build already that the patch works on my device). Since this kernel is included in the latest live images for Stonking, it impacts those live sessions as well, preventing installation on impacted platforms. Triaged as high importance since it has a severe impact on users of impacted laptops (keyboard is completely unusable) [0] https://github.com/torvalds/linux/commit/cb97bf3d4f91453b881acaf8e9f0cc47bb40b604 [1] https://lore.kernel.org/linux-i2c/20260928-b4-i2c-qcom-geni-preserve-source-clock-v1-1-9aded7552...@oss.qualcomm.com/ [2] https://launchpad.net/~mitchellaugustin/+archive/ubuntu/qcom-kbd-fix ** Affects: linux (Ubuntu) Importance: High Assignee: Mitchell Augustin (mitchellaugustin) Status: Confirmed ** Affects: linux (Ubuntu Stonking) Importance: High Assignee: Mitchell Augustin (mitchellaugustin) Status: Confirmed ** Also affects: linux (Ubuntu Stonking) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Stonking) Status: New => Confirmed ** Changed in: linux (Ubuntu Stonking) Importance: Undecided => High ** Description changed: The latest Stonking 7.3 kernel and daily images contain this patch [0], which selects a clock rate that is incorrect on some variants of the Snapdragon X2 Elite platform (and potentially others using similar keyboards).
