This issue prevents booting the installation disk with DVDs burned from the
following ISO images:

openSUSE-Tumbleweed-DVD-i586-Snapshot20180213-Media.iso
openSUSE-Tumbleweed-DVD-i586-Snapshot20180314-Media.iso
openSUSE-Tumbleweed-KDE-Live-i686-Snapshot20180314-Media.iso

Each image was verified by sha256sum before burning, and after burning, the
original ISO image and the new DVD were both mounted, then compared to each
other.  All verification was good.

Boot fails for any of the options that try to launch a Linux kernel from the
DVD, i.e., "Installation", "Upgrade", "Rescue System", or "Check Install
Media".  The progress box ("Starting...") comes up, runs through "Loading Linux
Kernel" to the 100% mark, then the screen blanks momentarily, there is a flurry
of boot-progress activity text, then the kernel panic.  The entire thing occurs
within a couple of seconds of the screen change.



Reproducible: Always

Steps to Reproduce:
1. Load installation DVD for affected release -- see above.
2. Boot from DVD, and select "Installation" after the initial bootsplash.
3. Wait through the "Loading Linux Kernel" progress dialog.
4. Watch the ensuing system crash.
Actual Results:  
Kernel panic/system crash.

Expected Results:  
Entry into installer screens.

This appears to be a regression; I have no problem booting the DVD for the
20170129 snapshot of Tumbleweed (the most recent I have available prior to
this).  It is also possible, however, that the regression is much more recent;
the 20180213 Tumbleweed snapshot (which fails) reports kernel 4.15.2-1, but I
am able to successfully boot kernel 4.15.0-10 (from a Kubuntu 18.04-beta1
disk).  Other relatively recent kernels (4.12.7, 4.13, and 4.14.12) from
various distributions also boot successfully.

The target machine is a Toshiba Tecra M5 laptop, model ST8112; I can provide
further hardware information as required -- please specify.  Of potential
interest, however:  I have two of these Tecras, almost twins, but one uses an
NVidia Quadro NVS 110M/128 MB graphics adapter, and the other has integrated
Intel 945GM graphics.  The NVidia machine crashes as described here; the Intel
one is unaffected, i.e., the above-noted Tumbleweed snapshots boot without
incident.

Finally, please see the attached file, containing a trace of the kernel panic
as dumped to my screen.  Hopefully this will be helpful.
