Description of problem: After updating to kernel-5.10.8, touching the screen of my Lenovo Yoga X1 2nd generation causes the system to instantly freeze, requiring hard reset. Version-Release number of selected component (if applicable): libwacom-1.7-2.fc33.x86_64 How reproducible: Always Steps to Reproduce: 1. Touch the screen 2. 3. Actual results: Total lockup requiring hard reset Expected results: Functional system Additional info: Downgrading to kernel 5.10.7 is a workaround. Apparently, there is a patch in the works. Upstream bug report: https://github.com/linuxwacom/input-wacom/issues/230#issuecomment-764589102 Bug report against kernel with additional documentation is Bug 1918486, but I wanted to get the attention of the appropriate maintainer ASAP.
Does the kernel update in Bug 1918486 fix the issue? libwacom is just a glorified text file database so it's not the cause of this issue.

Yes, that update solves the problem. I posted here because of the link in the other report to a patch to libwacom that indicated it was the fix. Thanks.
unfortunately, libwacom is the first place people file bugs and it's virtually never the actual cause of the bug, so any bug linking to libwacom is usually a false positive. Thanks for the update though, I'm marking this as duplicate. *** This bug has been marked as a duplicate of bug 1918486 ***
