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.
