Boot process stops at Load initial ramdisk

English Install/Boot/Login

I have installed Opensuse Leap 15.2 on an older Asus netbook, as dualboot with Windows 10, since I need this OS for some special applications.
Whenever I boot into the default Opensuse Leap 15,2 (main entry in Grub) I get the message “Loading initial ramdisk” and nothing happens.
If I choose “Advanced options for Opensuse Leap 15.2” and then chooses the last of the three options “Opensuse Leap 15.2, with Linux 4.12.14-lp151.28.52-default” the computer boots and get to the desktop.

The other two options under advanced options “Linux 5.3.18-p152-41-default” and “Linux 5.3.18-p152-19-default” also stops with the message “Loading initial ramdisk”.
Could it be an ACPI problem? - I have had that before with this computer. On the other hand - why should this only be connected to some kernels?
I do not know how to test it - where to put the no acpi option in Grub and to add it permanently if it works.

Thank You for any help!

The simplest way to edit the boot command line, is with Yast Boot loader. Use the “Kernel parameters” tab.

Thanks - the acpi=off option was already present in the Grub menu in the kernel parameters tab in Yast. It makes no difference. I wonder why I can only boot some older kernel - it is like the newer kernels is either not present or active/available?

I don’t know the cause.

A couple of suggestions:

(1) Edit “/etc/zypp/zypp.conf” (as root). Look for the line:

multiversion.kernels = latest,latest-1,running

and change it to:

multiversion.kernels = oldest,latest,latest-1,running

That way, your working kernel won’t be removed until you manually remove it.

(2) There was a new kernel update today. Try that, and see if it boots.

(3) If that does not work, file a bug report.

Hi
Then I would remove that option acpi=off that’s a last resort option IMHO… what about graphics card, not a dual gpu setup?

Test booting a simpler kernel command line. Strike the e key with highlight on a problem kernel selection, remove quiet, showopts and splash=silent from the line beginning linu, append to that line plymouth=0 and noresume, then proceed to try to boot. If it helps, try adding/removing one change at a time until the offender is identified. If it works, the change(s) can be made permanent via /etc/default/grub.

Hi again, sorry for the late reply. I removed the acpi=off boot parameter and then it boots perfectly. I remember that I added this parameter in order to make the installer work, but since it has obviously been at showkiller…
Thanks for the interest!
