i2c_hid module randomly dies and needs to be restarted

[wmdiem]

From 4.15.0-24 (not in 4.15.0-23) i2c_hid spams the log with messages like this:

[ 6079.727465] i2c_hid i2c-ELAN0630:00: i2c_hid_get_input: incomplete report (14/65535)
[ 6079.733692] i2c_hid i2c-ELAN0630:00: i2c_hid_get_input: incomplete report (14/65535)

It then randomly stops working (and stops spamming the log), and there is no trackpad response until I reload the module.

Again, this was introduced in 4.15.0-24.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1793584

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Would it be possible for you to test the proposed kernel and post back if it resolves this bug?
See https://wiki.ubuntu.compo/Testing/EnableProposed for documentation how to enable and use -proposed.

Thank you in advance!

[wmdiem (wmdiem)]

Thanks for the response.

Unfortunately I've since installed Mint. Do you know if there is a way to
install the proposed Ubuntu kernel in Mint? (This is my main machine, and
I'm not keen to partition the disk as a test, or wipe the current system. I
would try booting off a flash drive, but there is no easy way that I know
of to change or update the kernel in the image.)

Please try this kernel:
https://people.canonical.com/~khfeng/i2c-hid-elan/

[Kai-Heng Feng (kaihengfeng)]

Please ignore my last comment. I forgot to add your device id.

[Kai-Heng Feng (kaihengfeng)]

Also, can you attach full dmesg?

[Kai-Heng Feng (kaihengfeng)]

Ok, please try the kernel inside the link.

[wmdiem (wmdiem)]

Okay, have installed the new kernel.

1) I got an error
installing linux-headers-4.19.0-1-generic_4.19.0-1.2_elan+i2c_amd64.deb
because of unmet dependency, but I installed with "--force-depends".
2) The log is still getting spammed with "incomplete report" errors.
3) But the touchpad is working for the moment. It has only been up for a
few minutes. I'll keep running it and see if it continues to work. And
report back.

Okay, I haven't yet lost the trackpad completely, but twice now tap to
click has stopped working. The first time I rebooted to make sure it had
actually been working under the test kernel (I was pretty sure it had, but
wanted to confirm). The second time I removed and reloaded the i2c_hid
module; tap to touch returned, but there now a visible jitter in moving the
cursor.

Also, right click doesn't work (ever) under the test kernel (by right click
I mean depressing the pad itself while touching the right side of the pad.
Double-tap still works to simulate right click.

Further, if I reload the module, the error changes (note the numbers at the
end):
[ 1451.670747] i2c_hid i2c-ELAN0630:00: i2c_hid_get_input: incomplete
report (707/65535)

Note that it is on reload that the jittery cursor movement starts (it looks
like the cursor position is being updated ~10 times a second, rather than
more than 30 times a second).
