Subject: Re: [regression] Bug 216946 - Toshiba satellite click mini l9w-b: touchscreen: no touch events with kernel 6.1.4

Hi Thorsten,

travelling at the moment, but I’ll try. Not really into bisecting kernel issues, but let’s see where this goes. Another issue is, that I don’t have a Toshiba Mini Click myself, so I need to build the test Volumio images (volumio.org) with the different 5.16-rc kernel patch versions for a colleague to work with, hopefully  he has time to do this.

Thanks - Gé
