[Bug 1188970] Xorg crashes with a segmentation fault when a secondary USB display using DisplayLink is connected
https://bugzilla.suse.com/show_bug.cgi?id=1188970 https://bugzilla.suse.com/show_bug.cgi?id=1188970#c44 --- Comment #44 from Thomas Zimmermann <tzimmermann@suse.com> ---
Created attachment 851469 [details] Xorg.0.log showing the degmentation fault.
The Xorg log here is a segmentation fault in the X server AFAICT. The kernel error is not a segmentation fault. It's warning about invalid ref-counting.

I tend to think that both are unrelated. A kernel warning shouldn't crash the X server. And there are other things happening in the kernel after that warning shows up. -- You are receiving this mail because: You are the assignee for the bug.
