No, it is just that my diagnostics don't apply cleanly before the commit that enabled RCU_BOOST. Ah! I see. No, I just made my script dump all the RCU debugfs information, I wasn't trying to provide guidance. ;-) > > Attached is collectdebugfs-dileks.log, my current kernel-config and a > > build-script to generate Debian packages. Hmmmm... The system died within 30 seconds? The usual way that RCU hangs the system is by memory exhaustion: grace periods stop advancing, RCU callbacks therefore never get invoked, and RCU-protected memory therefore never gets freed. But I guess if your workload freed RCU-protected data fast enough, the system could hang quickly. > > $ LANG=C ./collectdebugfs.sh 2>&1 | tee collectdebugfs-dileks.log > > > > I will do a 2nd run with PREEMPT_RCU enabled. > > > > - Sedat - > > > > Here the results from the 2nd-run (PREEMPT_RCU enabled). OK, and the grace periods clearly stopped advancing early on. Beyond that point, the per-CPU kthread is blocked, but RCU has some work for it to do. So someone has called invoke_rcu_cpu_kthread(), but rcu_cpu_kthread() is still blocked. I don't see a bug right off-hand, but it is early in the morning for me, so I might easily be missing something. Hmmm... The synchronization between these two assumes that the per-CPU kthread is always bound to the respective CPU, so if was somehow being migrated off, that might explain these results. I will add some more diagnostics, test them locally, then push out an update. Seem reasonable? And thank you again for the testing!!!
