RL 8.6 Bug; "Soft Lockup"

On jaguar with is running 8.6 I keep getting a message at times referring to a " Soft Lockup Bug". Dose it lockup my machine? YES!! But there is nothing “soft” about it. Does any know what this “Soft lockup bug” is?? Is there any way to KILL it?? Will a can of Industrial Strength RAID! kill it?

Maybe this will help: What are all these "Bug: soft lockup" messages about? | Support | SUSE

Yes, I know it’s a SUSE article, but it might help. You may want to see if something (program/process) was overloading your CPU during this time as well. Some other posts I found (HPE) hint it could be hardware-related also.
