Hi, I have a Lenovo t490s, and sometimes at boot the touchpad is not working. When it fails the syslog says: psmouse serio1: elantech: assuming hardware version 4 (with firmware version 0x7f3001) psmouse serio1: elantech: Synaptics capabilities query result 0x90, 0x18, 0x0f. psmouse serio1: elantech: Elan sample query result 00, 2f, c9 psmouse serio1: elantech: Trying to set up SMBus access elan_i2c 0-0015: failed to get FW checksum: -71 elan_i2c: probe of 0-0015 failed with error -71 Is it a known issue? I'm using a vanilla 5.7.9 kernel. -- Matteo Croce perl -e 'for($t=0;;$t++){print chr($t*($t>>8|$t>>13)&255)}' |aplay
