Lenovo touchpad intermittently stops working with i2c_designware errors

[Josh Rosenberg]

Hi. 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

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".

Hi Rosenberg,

Could you try to update firmware to check out it again?

If the issue is still there, could you try upstream kernel:
https://kernel.ubuntu.com/mainline/v6.10-rc4/

and upload dmesg after the issue is happened.

Note, secure boot should be disabled when using upstream kernel.
