extract of journalctl with nouveau crash
Last opensuse tumbleweed version:
I'm using the nouveau driver with the kernel 4.3.0-1-xen (geeko@buildhost) (gcc
version 5.2.1 20151008 [gcc-5-branch revision 228597.
My hardware is a HP proliant ML350p Gen8 with an Nvidia quadro 4000 video card
with 2 screens (DVI + DP1) using a extended layout;
I have some locks occurring randomly when
- loading some programs (Yast, Xine; Shishen etc...)
- or starting a video in the browser (seamonkey on www. youtube or news site
(www.lesoir.be, www.lemonde.fr)
- reactivating a session (lock occurs when moving mouse or pressing keyboard)
the desktop freezes or is bad redraw and locks thereafter.Keyboard is inactive
and I must do a hard reset.
Some time the hardware indicate a non maskable interrupt
This lock occurs randomly since kernel 4.2
In journalctl I see a crash of the nouveau driver.
Here the output when locking by loading Yast:

I'll attach a long extract of journalctl after a lock occuring when
reactivating a session</pre>
