Booting with the live USB from SuSE Leap 15 just ended with MSI laptop in a hanging state. No F-screens of course, no terminal.
So I am note sure how I should do some "dmesg" like the guys did in the archlinux bugticket.
Yes, when you system is dead, there's no way to do that.
Is there some way to enter a logging command on the grub screen of the live USB, which is written to the USB stick then? Did not find any hint on Internet.
The only way I know of is to use a serial console. Your laptop probably doesn't have a serial port though :-(
Just tried Leap 15 KDE Live on USB stick once more several "NMI watchdog: BUG: soft lockup - CPU0 stuck for 23s ! [plymouthd:468]" then "INFO: rcu_sched self-detected stall on CPU" "0-...:(14999 ticks this GP) idle=62e/1400...some zeros..1/0 softirq=1500/1500 fqs=7499 (t=15000 jiffies g=362 c=361 q=390) then some NMI watchdog again, 6 times then "INFO: rcu_sched self-detected stall on CPU" again and the tick message with different numbers. These messages simply repeat, partly with different numbers.
Someone suggested to keep it running because it will sort out itself, but that does not occur.
I have also seen this problem in the past, and it only delayed things for bit, never led to a complete halt. Your situation is likely very different, even if the symptoms are similar.
I restarted the Leap 15 KDE Live USB stick this time entering "nomodeset" before "splash=silent" as with Ubuntu, and there is some KDE screen with low resolution coming up where I can get some dmesg output.
Wait - with nomodeset, your system does not grind to a halt? You have access? That seems to indicate a graphics driver issue? -- Per Jessen, Zürich (17.3°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
