Is this still happening with 4.5.y? Yes (4.5.5-201.fc23.x86_64). For the test I removed "psmouse.proto=imps i8042.reset i8042.nomux=1" from /etc/default/grub and updated grub. After reboot touchpad does not work at all and after suspend keyboard behave strange again. Regards, Damjan Fresh install of fedora 24. Still doesn't work.

(In reply to Josh Boyer from comment #2) > Is this still happening with 4.5.y? Still happening with: $ cat /etc/redhat-release Fedora release 24 (Twenty Four) $ uname -a Linux nb2079 4.7.4-200.fc24.x86_64 #1 SMP Thu Sep 15 18:42:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux However, I removed "psmouse.proto=imps i8042.reset i8042.nomux=1" from /etc/default/grub and updated grub. Rebooted and touchpad is not working. However I found another "workaround": # cat /sys/devices/platform/i8042/serio2/crc_enabled 0x00 With the following command touchpad start working, can change settings in gnome "Mouse $ Touchpad", touchpad is automatically disabled while typing and touchpad and keyboard is working fine after sleep/suspend :) # echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled # cat /sys/devices/platform/i8042/serio2/crc_enabled 0x01 I created unit file so the "echo" command is applied after each boot... Thanks for making the difficult task of finding a good workaround. I think it should be easy enough now to add this in the kernel for all this range of touchpads. It appears I have other bug reports with Elantech touchpads that are behaving strangely while used in PS/2. These touchpads can also communicate over SMBus, and this bus solves most of the issues (simply as this is the one used under Windows). To check whether yours can also communicate over SMBus, I'd like you to give me the output of: - acpidump - modprobe i2c-dev - i2cdetect -l - i2cdetect N where N is the SMBus adapter enumerated by "i2cdetect -l" When in "i2cdetect N", accept to test the full range of device. If there is one device answering at 0x15, there is a huge chance the device talks over SMBus too. Here is the output of the i2cdetect commands:
# i2cdetect -l
i2c-0 i2c i915 gmbus dpc I2C adapter
i2c-1 i2c i915 gmbus dpb I2C adapter
i2c-2 i2c i915 gmbus dpd I2C adapter
i2c-3 i2c DPDDC-A I2C adapter
i2c-4 i2c DPDDC-B I2C adapter
i2c-5 i2c DPDDC-C I2C adapter
i2c-6 smbus SMBus I801 adapter at 3040 SMBus adapter
# i2cdetect 6
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-6.
I will probe address range 0x03-0x77.

Thanks for the logs. Looks like the chances your touchpad can also be controlled over SMBus are high. I tried all day pushing a koji build for you to test, though it seems I can't get one to compile (the mock buildroot step fails for f25). I'll try tomorrow again and I'll provide some instructions. https://patchwork.kernel.org/patch/9363675/ ^^^ upstream patch to enable CRC on PS/2 for this model, and which should solve the issue until I2C gets used. *********** MASS BUG UPDATE ************** We apologize for the inconvenience.
