When using my Yoga 6 13ALC6 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 reported this to Ubuntu, and they instructed me to report it upstream here. 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.

Is your BIOS up to date? Yes, it is. From DMI: dmi.bios.date: 03/26/2024 dmi.bios.release: 1.22 dmi.bios.vendor: LENOVO dmi.bios.version: H6CN22WW(V1.15) Per https://support.lenovo.com/us/en/downloads/ds549424-bios-update-for- windows-10-64-bit-yoga-6-13alc6 , H6CN22WW is the most recent version, released April 16 of this year. (I don't know why that date is later than the one reported by DMI.)

"# dmidecode | grep AGESA" That string doesn't appear in my dmidecode output. I also didn't see anything called AGESA when I booted into UEFI and looked around.

In any case, this timeout is something that comes from the hardware. The method that is timing out did have a rework recently (commit 197ecadad8428 ("i2c: designware: Implement generic polling mode code for Wangxun 10Gb NIC")) but I don't think it's likely to change your scenario. I use I2C touchpads all the time on AMD systems both reference and OEM systems. This hasn't happened to me, but this to me looks like a BIOS issue, and I think you should raise it with Lenovo.
