Kernel (plasma?) problem

Hi lol!

3 days ago i made a clean install of leap but i think i’m having problems with the kernel. I typed journalctl -fe and obtanined:

nov 13 18:47:04 linux-893x.suse kernel: --- end trace fd06addc2316d810 ]---
nov 13 18:47:04 linux-893x.suse kernel: **BUG: unable to handle kernel NULL pointer dereference at 0000000000000004**

nov 13 18:47:04 linux-893x.suse kernel: Oops: 0000 #1] PREEMPT SMP

and at the end of this output:

nov 13 18:47:31 linux-893x.suse kernel: **NMI watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [MediaTimer #1:8035]**

(red messages are red in command line) What can i do?

my inxi -CMS is

Hi lol!

3 days ago i made a clean install of leap but i think i’m having problems with the kernel. Suddenly, the workspace i’m in turns black except for the application i’m using. i lose the panel and if i right click, no menu is desplayed. I can shift to other workspaces, which are a black screen too. I also note that the windows “blink” when i change from one window to another or if i close one of them. Twice the system has “frozen” and i’ve had to do a “hard shutdown”. Can you help me?

I typed journalctl -fe and obtanined:

nov 13 18:47:04 linux-893x.suse kernel: --- end trace fd06addc2316d810 ]---
