Comment # 37 on bug 944978 from Takashi Iwai

> Hi. It is possible to increase the level of system log?

Well, dmesg output already contains the information.  You can increase the
console log level (run "dmesg -n 8", for example).  Also, you might have a
better chance with kernel-debug package instead of kernel-desktop.

You can find some old kernels in OBS home:tiwai:kernel:3.18, 3.19, 4.0, etc. 
They contain the latest stable updates of SUSE kernels.
