This issue doesn't happen on SLE12-SP2, openSUSE 42.1 and openSUSE 13.1.

Were you actively using the displaylink for additional outputs in those distributions? If not, it is possible it would still crash in there, but didn't just because it wasn't auto-configured as it is in 42.2. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.suse.com/show_bug.cgi?id=1011570 http://bugzilla.suse.com/show_bug.cgi?id=1011570#c3 --- Comment #3 from Michal Srb --- The problem is that modesettings' FreeRec function zeroes pScrn->driverPrivate and then calls function that tries to use it. It was fixed upstream in commit a41a171bcbae9aeafac2865faa904f15d9b59925, I'll backport it. -- You are receiving this mail because: You are on the CC list for the bug.

This is a dupe of boo#981268. Michal, can you mark this once you've ported U_modesetting-set-driverPrivate-to-NULL-after-closing-fd.patch over to Leap 42.2? -- You are receiving this mail because: You are on the CC list for the bug.
