Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting for once, to make this easily accessible to everyone. Dmitry, Edward seems to have some regression with Xinput Controllers no Longer Working since v6.8..v6.9 and still not working with mainline. The thread starts here: https://lore.kernel.org/all/CABRw72orHLEqpAS%3DcW1ThGkVUW0juqc7Y_-N2%3Do-k0rSqgpLxA@xxxxxxxxxxxxxx/ Dmesg files are attached to the parent of this mail. I briefly looked into them but no obvious problem jumped out to me untrained eyes. Edward, with a bit of luck Dmitry might have an idea what's wrong here. But if not you might need to perform a git bisection to find the change that broke things: https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html That process would also rule out that some config change on the Fedora side causes this.

P.S.: let me add this to the tracking: #regzbot report / #regzbot introduced v6.8..v6.9 #regzbot title input: Xinput Controllers No Longer Working #regzbot ignore-activity
