Re: PROBLEM: ETPS/2 Elantech Touchpad dies after resume from suspend to RAM‏

Hi,

I have added a bug report on https://bugzilla.kernel.org/show_bug.cgi?id=107971

Further info:

The touchpad (/sys/devices/platform/i8042/serio1/input) just totally gone after resume.

before suspend:
#ls /sys/devices/platform/i8042/serio1/
bind_mode drvctl paritycheck reg_10 reg_23 resolution
crc_enabled firmware_id power reg_11 reg_24 resync_time
debug id protocol reg_20 reg_25 subsystem
description input rate reg_21 reg_26 uevent
driver modalias reg_07 reg_22 resetafter

after resume:
#ls /sys/devices/platform/i8042/serio1/
bind_mode drvctl id power uevent
description firmware_id modalias subsystem


Thanks.
