I have a spare machine and I can leave it running for days. Can you please point me to the parallel benchmark that triggered rcu stalls? @michaeljclark

I got a OOM Out of memory: Kill process 32539 (ld) score 317 or sacrifice child Killed process 32539 (ld) total-vm:652140kB, anon-rss:648564kB, file-rss:56kB, shmem-rss:0kB oom_reaper: reaped process 32539 (ld), now...

@michaeljclark Just wanted to check if you need more testing or the patch can be merged.

This issue is no longer present after we got rid of local interrupt controller driver in 4.19. We can close this issue.
