I get the impression that some people think that I am talking of one particular computer. This is NOT the case. I am talking of several different computers where I experienced similar effects. Also I conclude from some of meanwhile received messages here: Yes, I am NO DEVELOPER. I am an advanced user only, but I usially don't fiddle around in depths as necessary here.

Here's one option you never even mentioned:
Put the disk in a different machine, install and update the core OS, then transplant it into the new, problematic machine and see if that fixes it.
Partially I mentioned that already. :) I confirmed that I was able to install Leap 15 on one machine (here I only had extreme problems with ACPI, but the initial kernel survived them and continued booting, so I was able to proceed. Doing updates without locking the kernel, ended up in a system that did not boot any more, it stopped directly in the line "Loading initial ramdisk ...". Selecting then the original kernel version in grub2 did boot again. -> This is indicating that something became worser with the newer kernel. So I re-installed from scratch and locked then the kernel in Yast before running the first update, all other updates were done. The result was an updated system, still running the original setup kernel, and not running worser than before. (So everything is updated except the kernel, therefore ACPI related things still not working.) -> Many things changed by update, except kernel, and system is (still) booting, but not supporting ACPI. Again indicating that the kernel is the reason. Then "fvogt" helped me to install kernel 4.20, and after that everything was working well, including ACPI. (Now with new kernel 4.20). -> This again indicates a kernel issue. With laptops this is not easy to do! Some have soldered-in SSD on the mainboard, others have a SSD as plugin-card. Usually such (current) ones often cause this problems or even totaly refuse to boot from the stick (Grub comes, but booting the installer freezes as above). In addition, I cannot disassemble a brand new laptop I want to sell, please understand. So what I want to do is: Have a stick at hands which has the 4.20 kernel (or at least a 4.19). When such computer appears again, I can simply try that stick and give feedback. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
