Try searching bugzilla for that one. Very annoying, I have had it a few times over the years.
Oh, I have until my little fingers hurt. All the way down to core.c in the kernel. The problem is there are a number of factors that come into play. There is the nomodeset angle, and apic angle (on by default with SMP), then there is the high load angle. There have been a ton of perf patches flying around on LKML just in the past few days. As well as a few addressing nmi checks. It all boils down to unless you are one of the kernel devs, with a niche in multi-cpu pre-init, or you just have a month long sabbatical you are willing to devote to chasing the issue down, you are pretty much stuck. It was comical to see how many CPU stuck for 23 sec. posts there are out there. I know there were no issues in 4.14, there are issues in 4.16 -- those are about the only 2 hard data points I have. -- David C.
