Comment # 20 on bug 917411 from Takashi Iwai

OK, so we go back to square, but with a slight more knowlege.  At least, this
is a real sudden death and the complete freeze including the kernel.  The bad
thing is that it's still almost impossible to even guess what weng wrong in the
current situation without error logs.

A few things you can still try are:
- Try kernel-debug package.  This might catch some issues before the hang or
might show something at hang.

- Increase the kernel log level.  Run "dmesg -n 8" once.  This makes the kernel
debug messages logged, too, so worth for all kernel flavors.

- Use the newer kernel versions (3.18.x, 3.19).  The packages are available in
OBS Kernel:stable and Kernel:HEAD repos.
