I'm having the same issue with my Mi Notebook Pro (I'm using debian buster with 4.18 kernel). To fix that I compiled the i2c-hid module replacing dev_err with dev_err_once - so I still can see the "incomplete report" but only once and not 20 times per second (during sliding finger over the touchpad).
Of course it fixes the problem only if the error message is identical(!) as it was in my case. For those who would like to give it try here is the repo: https://github.com/opokatech/i2c-hid-fix -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1784152 Title: i2c_hid_get_input floods system logs Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu 4.15.0-29.31-generic 4.15.18 After upgrading to kernel version 4.15.0-29 from 4.15.0-23, the system logs are flooded whenever I move the cursor with my touchpad. It looks like this: i2c_hid i2c-ELAN1010:00: i2c_hid_get_input: incomplete report (14/65535) i2c_hid i2c-ELAN1010:00: i2c_hid_get_input: incomplete report (14/65535) i2c_hid i2c-ELAN1010:00: i2c_hid_get_input: incomplete report (14/65535) i2c_hid i2c-ELAN1010:00: i2c_hid_get_input: incomplete report (14/65535) etc... This problem did not occur on the previous kernel version so there must have been a change to the "drivers/hid/i2c-hid/i2c-hid.c" file. This seems to be fixed in a recent commit here: https://github.com/torvalds/linux/commit/ef6eaf27274c0351f7059163918f3795da13199c I am currently running the older kernel version but would still like to be up to date without this flooding happening.
