** Description changed: After upgrading to 26.10 with 7.3.0-9 kernel, the touchpad of my Dell Latitude 5430 with BIOS 1.40.0 stops working. Manually binding and unbinding produces i2c_hid_acpi i2c-VEN_0488:00: device did not ack reset within 1000 ms It seems that the touchpads vendor is Cirque Corporation.

I briefly checked powertop and havent found any noticeable sign of that. Fix 2: Booting 7.0.0-x from 26.04 also makes it work. + --- + ProblemType: Bug + ApportVersion: 2.36.0-0ubuntu1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: ubuntu 3649 F.... wireplumber + /dev/snd/seq: ubuntu 3645 F.... pipewire + CasperMD5CheckResult: unknown + CasperVersion: 26.10.2 + CloudArchitecture: x86_64 + CloudID: nocloud + CloudName: unknown + CloudPlatform: nocloud + CloudSubPlatform: seed-dir (/var/lib/cloud/seed/nocloud) + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 26.10 + IwDevWlp0s20f3Link: Not connected. + LiveMediaBuild: Ubuntu 26.10 "Stonking Stingray" - Official amd64 (20261013) + MachineType: Dell Inc.
