Hi, Here is another system with a similar problem: the touchpad randomly stops responding. This is Dell Precision 5470. I saw the issue with the 6.11 kernel series and BIOS 1.24. Now it is updated to
Dell Inc. Precision 5470/02RK6V, BIOS 1.26.0 09/12/2024 and Linux 6.12.1-1.el9.elrepo.x86_64, and the touchpad just broke again.

What information would be useful to add? There is a question in the thread above about AGESA version, but I don't see the AGESA string in the dmidecode output on my system.

When using my laptop, I frequently experience the touchpad suddenly cease working. Sometimes there's a few seconds' warning with reduced responsiveness, and sometimes it's completely sudden. I experienced this in Kubuntu 22.04, and I still experience it after upgrading to 24.04. Output from kern.log when it happens often looks like this: 2024-07-09T21:31:51.573862-04:00 machinename kernel: i2c_designware AMDI0010:00: controller timed out 2024-07-09T21:31:51.577113-04:00 machinename kernel: i2c_designware AMDI0010:00: timeout in disabling adapter 2024-07-09T21:31:51.596828-04:00 machinename kernel: i2c_designware AMDI0010:00: timeout waiting for bus ready 2024-07-09T21:32:45.928870-04:00 machinename kernel: message repeated 2652 times: [ i2c_designware AMDI0010:00: timeout waiting for bus ready] The only workaround I've found is to sleep/hibernate or shut down the laptop; it always works again on reboot. Since I upgraded to 24.04, I sometimes have the additional problem that I can't sleep the laptop when this is happening. I get errors that say "kernel: Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7" when I try. Note that the problem did not happen between my most recent boot and the generation of the attached files via "ubuntu-bug linux".
