I'd be suspicious of these here commits: 77d1dfda0e79 ("sched/topology, cpuset: Avoid spurious/wrong domain rebuilds") 09e0dd8e0f2e ("sched/topology: Avoid pointless rebuild") bbdacdfed2f5 ("sched/debug: Optimize sched_domain sysctl generation") I tested them with regular hotplug, but suspend resume always is a tad funny.
