I downloaded the installation Leap 42.2 ISO from
https://software.opensuse.org/422/en and verified its SHA 256 checksum:

$ ls -l
insgesamt 4281368
-rw-r--r-- 1 magnus magnus 4384096256 Feb  2 00:44
openSUSE-Leap-42.2-DVD-x86_64.iso
-rw-r--r-- 1 magnus magnus        630 Feb  2 00:44
openSUSE-Leap-42.2-DVD-x86_64.iso.sha256
$ sha256sum -c openSUSE-Leap-42.2-DVD-x86_64.iso.sha256 
openSUSE-Leap-42.2-DVD-x86_64.iso: OK

I wrote the image to a verified and working USB stick with 32 GByte capacity
with
# dd if=openSUSE-Leap-42.2-DVD-x86_64.iso of=/dev/sdb

When booting this image on either a Lenovo Thinkpad X1 Carbon, 3rd gen or a
Lenovo Thinkpad T460p (bought 2016), the slash screen pops up. Selecting the
boot Linux item to start the live CD the kernel boots, but is interrupted by a
"Signal 11" message on the lower part of the screen.

Please advise how to further debug this issue.
