Comment # 42 on bug 1006417 from Egon Niessner

I tried to boot with a DVD containing
openSUSE-Tumbleweed-DVD-i586-Snapshot20161105-Media.iso
(it contains  kernel-default-4.8.6-2.1.i586)

During boot of the rescue system in save mode (and all selectable kernel
settings
before booting),
the rescue system crashes after loading the initrd
with the last message after backtrace
"DWARF2 unwinder stuck at resume_userspace +  0xe/0x13
 leftover inexact backtrace"

So tumbleweed is not bootable on a real i586 single core system.

(On a pentium 4 system with two 32 bit cores, this dvd can be booted.)
