Oh I see... probably mine is a different problem (attached updated output of dmesg). I thought the following error could be related to the issue:
amd_gpio AMDI0030:00: Failed to get gpio IRQ: -22 ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1609601/+attachment/5054229/+files/dmesg.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1609601 Title: i2c_hid: probe of i2c-ELAN0732:00 failed with error -61 Status in linux package in Ubuntu: Triaged Bug description: I'm using an HP Envy x360 M6-ar004dx with an AMD 7th-gen FX APU, and the touchscreen will not work. Dmesg shows i2c_hid reporting multiple "failed to reset device" error messages before finally failing to add it as an HID device with error -61. As far as I can tell, it's being detected as an ELAN touchscreen. I've seen reports that this error can be fixed in newer kernels, as the touchscreen uses GPIO interrupts which are fixed in versions 4.6 and later. Most of the information I can find indicates that 4.7 includes improved AMD support, but the mainline kernel build appears to be missing the AMD GPIO drivers, since I get a "failed to get GPIO interrupt" error. I've compiled my own 4.7 kernel from the mainline GIT, including the patches used in kernel-ppa/mainline and setting the right config flags for AMD GPIO, but that just gets me the same errors I'm seeing in 4.4.0-31-generic. For additional info, I'm attaching my dmesg output in its entirety.
