I have the same issue. Workarounds with driver recompilation are not really a good fit in my case since they require to set up a build system and also to enroll a MOK key for unsigned drivers to work because I have Secure Boot enabled. acpi_osi workaround disables touchpad on my system.
Until the bug is fixed, here's a quicker and easier way to filter these messages on syslog level inspired by https://askubuntu.com/a/21648: 1. sudo vi /etc/rsyslog.d/01-blocklist.conf (any name after "01-" part will work) 2. Add this line: :msg,contains,"i2c_hid_get_input" ~ 3. Save the file and restart rsyslog service: sudo systemctl restart rsyslog You can make the filter more specific, i.e. filter only "incomplete report" messages instead of suppressing all output of messages containing "i2c_hid_get_input" but latter case works just fine for my purposes. Hope this helps. -- 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.
