1. Please describe the problem: On either a old Lenovo ThinkPad X1 Yoga (Gen1), or a new ThinkPad X13 Yoga (Gen1) touching the screen with the stylus freezes the system. This occurs after the 5.10 kernel update. Booting the 5.9 kernel solves the issue. No messages can be found in syslog. It seems logging just stops. 2. What is the Version-Release number of the kernel: kernel-5.10.9-201.fc33.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Switching to the 5.10 kernel seems to have introduced the issue. Booting the 5.9 kernel prevents the crash. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Boot the 5.10 kernel on a suitably equipped machine, and try to use the stylus. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Not tested. 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. TBD.
I have to correct the above statement regarding the version where it broke. My user reported slightly misleading information ;-) This is based on my own testing on the X13 Yoga. Working kernel-5.9.16-200.fc33.x86_64 Working kernel-5.10.7-200.fc33.x86_64 Broken kernel-5.10.8-200.fc33.x86_64 Broken kernel-5.10.9-201.fc33.x86_64
An external USB Wacom Bamboo tablet does not cause the crash (tested with kernel-5.10.9-201.fc33.x86_64)

I have a similar problem on my dell XPS13 2in1. The touch screen and the pen stop working (otherwise the system still works, however I did also experience a crash). This is under wayland. 5.10.7-200.fc33.x86_64 works, 5.10.8-200.fc33.x86_64 and 5.10.9-201.fc33.x86_64 do not.

It seems a more recent kernel update fixed the issue. Not quite sure which one as pen input was avoided due to these freezes. Right now the systems are on kernel-5.10.19-200.fc33.x86_64 As such I'm closing this.
