--- Comment #5 from Philippe Condé <conde.philippe at skynet.be> ---
hello,

it is kde5  (KF5). 
With opensuse Tumbleweed we do a global update (snapshot). Difficult to see
thereafter if this is due to KDE or the kernel. 

Three examples from journalctl:

the very first error after the boot message: the lock occurred during
reactivation of the session:

there are a lot of this messages  and then errors about kscreenlocker 
ov 16 00:10:32 hpprol2 kernel: nouveau 0000:0a:00.0: fifo: read fault at
2000000000 engine 07 [PFIFO] client 06 [PFIFO] reason 00 [PT_NOT_PRESENT] on

Nov 16 00:10:32 hpprol2 kernel: nouveau 0000:0a:00.0: fifo: fifo engine fault
on channel 30, recovering...

the only common process in all case is nouveau
