Leap 15.3 on front slot SSD-Drive

Since 15.3, after 1-10 times of normal booting I get a hang on boot.
Then hard shutdown, boot again.

If I see many "kvm: disabled by bios" messages like 3 or more, then this is a
good sign for correct booting later. A bad sign is the turning wheel never
ending.

var/log/messages doesn't give me a clue where it hangs.


The bad sign from "last | more":
reboot   system boot  5.3.18-150300.59 Wed Jun 15 09:47   still running
reboot   system boot  5.3.18-150300.59 Wed Jun 15 09:46 - 07:46  (-1:59)

The good sign:
hrd      pts/1        :0               Tue Jun 14 23:04 - 23:05  (00:00)
hrd      pts/0        :0               Tue Jun 14 22:34 - down   (00:47)
hrd      tty7         :0               Tue Jun 14 22:34 - down   (00:47)

The bad sign after just one normal boot:
reboot   system boot  5.3.18-150300.59 Wed Jun 15 00:34 - 23:22  (-1:11)
reboot   system boot  5.3.18-150300.59 Wed Jun 15 00:33 - 22:33  (-1:59)

Somewhere is a logic to prevent hanging all the time, unable to start Leap
15.3.
