@hookedbehemoth: Not 100% sure but it looks like you booted the old kernel (where the driver was builtin) with the new modules.

But the module containing the newer driver doesn't get loaded either because of symbols missing in kernels older than 4.19: [ 6.263647] i2c_amd_mp2: Unknown symbol i2c_get_dma_safe_msg_buf (err 0) [ 6.292760] i2c_amd_mp2: Unknown symbol i2c_put_dma_safe_msg_buf (err 0) I'm surprised that it worked at all for Kai and Stephan. The patch needs a few changes in order to be applied to older kernels, I forgot to mention it. -- 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/1787775 Title: touchpad not working on lenovo yoga 530 Status in linux package in Ubuntu: Confirmed Bug description: The touchpad is not working and does not show up in cat /proc/bus/input/devices on multiple kernels.
