Essentially, the Leap 15.1 GM kernel had the 4.19.y level of nouveau driver while the update driver has 5.0.y level. So something might have been broken by the upstream update... In anyway, please make sure that it's a nouveau problem; i.e. boot the new kernel with nomodeset and confirm that it can boot up properly. Once after that, go to Linux console (alt-ctl-F1), login there as root, and go to runlevel 3. % /sbin/init 3 Then reload nouveau forcibly % modprobe -r nouveau % modprobe nouveau % modprobe -r nouveau modeset=1 This should cause a problem again, and you may have a chance to get some kernel stack trace. -- You are receiving this mail because: You are on the CC list for the bug.

I don't expect that you can actually see the kernel stack trace on the running kernel by forcing nouveau driver load, but am interested in rather getting the message afterward. -- You are receiving this mail because: You are on the CC list for the bug.

Using nomodeset allows system to boot. This applies to kernel version 4.12.14-lp151.28.4.1 and 4.12.14-lp151.31.1. Running modprobe -r nouveau modprobe nouveau modeset=1 PC freezes. See attachment 806880 for screen shot of boot fail and modprobe output. -- You are receiving this mail because: You are on the CC list for the bug.

The dmesg reveals that it's likely the missing upstream fixes for DRM CEC stuff, which hits only on the recent nouveau and amdgpu. The fix is 5ce70c799ac22c142061c71aaeae518f04283472 drm_dp_cec: check that aux has a transfer function A test kernel with the fixes is being built on OBS home:tiwai:bsc1136978 repo. Could you guys check whether this works? Once after confirmation, I'll merge it to SLE15-SP1 branch (that is merged to openSUSE-15.1 branch in turn).

Thanks for the information, and apologies for the late reaction, as I've been on vacation in the last week.

I thought so, 1 week after 15.1 release announcement, but found a commit with your email address dated only 2-3 days ago. How did that happen?
