Comment # 9 on bug 990003 from Michal Kube��ek

Sorry for the delay, I thought I did write the comment already.

As far as I can tell, there is no sign of problem in your kernel log. In the
meantime, I learned that current openSUSE kernels are (unlike upstream ones)
configured to after 90 seconds on panic.

I'm afraid a kernel log from an actual crashed session would be needed. There
are two basic ways to get it:

1. Setup a serial console. This is easier but it requires a (real) serial
port which is rather rare on current hardware and a serial ("laplink") cable.
You would also need another machine to watch the serial console (a USB to
serial adapter can be used on that one).

2. Setup kdump as described e.g. on

 
https://doc.opensuse.org/documentation/leap/tuning/html/book.sle.tuning/cha.tuning.kexec.html

For a start, dmesg.txt file found in the directory with the dump which is
something like /var/crash/2016-08-16-14:41 should give some indication what
went wrong. The full dump (vmcore file) would give more complete information
but it's rather big and you should be aware that it contains a complete
snapshot of your system's memory at the moment of the crash.

Please let me know if you want more detailed instructions on one of these
options.
