...I was able to boot the Leap 15 installation DVD if I selected F5 and Safe Settings. I now need to find out exactly what this sets...
On vtty2: # cat /proc/cmdline apm=off acpi=off mce=off barrier=off ide=nodma idewait=50 i8042.nomux psmouse.proto=bare irqpoll pci=nommconf initrd=initrd splash=silent systemboot=1
Will you please explain what you were running when you entered vtty2?
Boot installation media F5 Select safe settings Wait for installation GUI to paint the screen Ctrl-Alt-F2 # cat /proc/cmdline
I experimented with the above "Safe Settings" and found that the only one that is required is acpi=off. And with thatthe system boots, but xosview only shows 3 cpus rather that the usual 7. Could the hyperthreading (if that is what they still call it) be disabled with lack of acpi? I tried the following options listed in kernel-parameters.txt, acpi=noirq, acpi=strict, and acpi=rsdt but none were successful. There are 26 more acpi related commands listed indicating a complex subsystem, but I do not know enough currently to experiment further.
Ideas welcome. Don
I am tired. I meant 4 cpus rather than the usual 8. Sorry. Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
