Thanks to your comment I also realized that journald still logs the dmesg driver spam which results in bloated journald log files as well. Few more steps is required to alleviate that:
1. sudo vi /etc/systemd/journald.conf 2. Uncomment Storage=auto and change it to Storage=none 3. Uncomment ForwardToSyslog=yes 4. Save the file changes and reboot This way logs are still forwarded to syslog where i2c_hid messages are filtered by the blocklist config file but you lose the ability to monitor logs using e.g. journalctl. I would like to emphasize that this is a temporary solution which works pretty well for my purpose but might not be a good fit for others. Please try to work around this behavior on kernel driver level first before resorting to syslog/journald shenanigans. Eagerly looking forward towards a fix for Elan touchpads. -- 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.
