journalctl gives the following output, there is an additional descriptor

There are reports [1,2] about Clock Speed of i2c bus on cannon-lake cpus that could be the reason at least for other devices so I tried with 180000000 and 216000000 but it did not help...

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

i tried kernel 4.17.2 and 4.18.RC6 on Ubuntu but the touchpad does not work.

i also tried this, the errormessages are gone with that "hack" but the touchpad still does not work:
https://bugzilla.kernel.org/show_bug.cgi?id=199911

so maybe the irq might be wrong but there is a another thing not working...

[marclandolt (marclandolt)]

There is a Solution now, a great guy at kenel.org fixed it:

On Ubuntu 18.04 you must download Kernel 14.18.rc6 form Kernel.org, apply 2 Patches and compile it.

Comment 68 https://bugzilla.kernel.org/show_bug.cgi?id=199911#c68.

Unfortunately still the same disconnection problems like on GE503VS.
