I am also experiencing the same issue on my Thinkbook 14p G2 ACH laptop. I also have my touchpad first become somewhat unresponsive for a few seconds and then completely lost input. Running `rmmod i2c_hid_acpi i2c_hid` before suspend, and running `modprobe i2c_hid_acpi` after resume usually resolves the issue.
My dmesg of a touchpad failure looks like this: ``` [20963.423965] i2c_hid_acpi i2c-ELAN06FA:00: i2c_hid_get_input: incomplete report (14/65280) [21054.169840] i2c_hid_acpi i2c-ELAN06FA:00: i2c_hid_get_input: incomplete report (14/65280) [21075.908772] i2c_designware AMDI0010:03: controller timed out [21075.912734] i2c_designware AMDI0010:03: timeout in disabling adapter [21075.933075] i2c_designware AMDI0010:03: timeout waiting for bus ready [21075.953175] i2c_designware AMDI0010:03: timeout waiting for bus ready [21075.973515] i2c_designware AMDI0010:03: timeout waiting for bus ready [21075.993702] i2c_designware AMDI0010:03: timeout waiting for bus ready [21076.013951] i2c_designware AMDI0010:03: timeout waiting for bus ready ``` My BIOS version is GWCN47WW (up to date, released on 2024/04/01), and my `amd_pmc` firmware version is 64.72.0 (hope this can help find the corresponding AGESA version). Kernel is `6.11.5-300.fc41.x86_64`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2072612 Title: Lenovo touchpad intermittently stops working with i2c_designware errors To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/2072612/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
