Lenovo Thinkbook 14 G4 IAP Touchpad not working

[LoLEpics]

Hello everyone! Since one of the last major updates, my touchpad has stopped working. I’ve found posts from people with similar problems, but their fixes didn’t work for me. As far as I can tell, the touchpad driver isn’t functioning correctly, but nothing I’ve found so far has fixed it. The only thing that worked was switching to kernel 6.1, but then my Wi-Fi (and likely other things) stopped working, so I didn’t pursue that further.

sudo dmesg | grep -iE "i2c|syna":

[    5.455076] i2c_hid_acpi i2c-SYNA2BA6:00: can't add hid device: -110 
[    5.456020] i2c_hid_acpi i2c-SYNA2BA6:00: probe with driver i2c_hid_acpi failed with error -110

_{Mod edit: changed terminal output to pre-formatted text by typing 3 backticks (```) on empty lines before & after the output}

I believe that this is the Culprit.
If anyone has an idea of how this could be fixed, I would really appreciate the help! Thanks in advance.

Also have issues with the touchpad of my thinkbook. Do you also receive the failed to load #IRQ27 at boot?

If so, it’s related to this bugreport:

block hook: mfd drivers break Lenovo IdeaPad touchpad (#295) · Issues · Arch...

Haven’t seen it fixed yet, but there is a workaround to get it working again:

sudo nano /usr/lib/initcpio/install/block

comment out the /drivers/mfd/ line, so it looks like this

#   add_checked_modules '/drivers/mfd/'

finalize with, if no errors, reboot and check

sudo mkinitcpio -P

Hi, I didn’t get the exact error, but it seems that IRQ27 was disabled!? I tried your workaround, and everything seems to be working now. Thank you very much!
