After updating from 5.1 to 5.2.1 in about 5-10 minutes of watching a Youtube video in Firefox I now get complete lock-up of video output and inability to shutdown using power button. Using "magic keys" allows me to reboot and get kernel log via `journalctl -b -1 -k`, here is relevant part: BUG: kernel NULL pointer dereference, address: 00000000000002b4 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 2 PID: 8200 Comm: kworker/u16:1 Tainted: G IO 5.2.1-1383.gd5bbc26-HSF #1 openSUSE Tumbleweed (unreleased) Hardware name: Gigabyte Technology Co., Ltd.
