Comment 13 for bug 1784152

Seeing it also on my Acer Swift 1 laptop with the newer Ubuntu 4.15 kernel releases (newest as of this writing is 4.15.0-35-38, and the issue is present in that build) and also with the mainline 4.18.10 release. My touchpad is also an Elantech, but is a different model from the original report. My touchpad is reported as ELAN0501 instead of ELAN1010 in the dmesg spam, but otherwise, it's exactly as reported (also reporting 14/65535).

Changing the touchpad mode to basic in the UEFI does eliminate the dmesg spam, but that's because it switches it to PS/2 mouse emulation mode, no longer using the I2C bus at all. The acpi_osi= parameter disabled the touchpad when I tried it.
