I am getting the same bug. I can login via KDE Plasma but starting any web browser (firefoc, chrome, konqueror) fails and system locks up requiring power down/up. This is with any 4.19.2 kernel. Setting nvidia-drm.modeset=0 in the kernel boot line results in a working system. Also, the BUG message does not appear.

The kernel log message is:

I had the issue described by the OP (xfwm4, 4.19.2) and this kernel patch fixed it for me: [PATCH v2] drm: set is_master to 0 upon drm_new_set_master() failure - Sergio Correia

th6mas · December 1, 2018, 3:44pm

Does anyone know how to update the kernel 4.19.4-300.fc29.x86_64 on Fedora 29 with this patch (beginner level)? Thanks!

sambo57u · December 3, 2018, 6:30pm

Fedora has included the patch in 4.19.5-300 and 4.19.6-300 kernels.
