I just tried Leap 15.1 Build 416.2 on my laptop and found and have seriosu
issues with reliability.

After an undetermined time, the system will lock up completely, finally even
unable to move mouse pointer around.

dmesg shows plenty of call traces from nouveau, please see attached log file.

1. The issue appears to go away when passing nouveau.modeset=0 to cmdline - but
also renders the nvidia gpu unusable at runtime. Well, at least the system is
stable then ...
2. DRI_PRIME=1 glxinfo hangs up

This issue appears related to #1123900 which has been closed recently.

If there is something I can do to resolve this, please let me know.
