Hi, Paul:
I found the linux-stable-4.1.15 with rt15 patches boot hang sometimes.
Hardware is Grantley-EP and WildcatPass.
No response by sysrq.
Did you found any issue about this? Or how can I address this issue?
Attached kernel config.
Thanks,
Pengyu

I see something similar in post-4.1 mainline, but only when CPU hotplug
is enabled and only under extreme stress. Which is probably not the
case during your boot-up. But please see below.

The "stalling" CPU is idle, which is a quiescent state and therefore
should not stall grace periods. But please see below...

The reason that the idle CPU is not being recognized as a legitimate
quiescent state is that the rcu_preempt grace-period kthread is not
being allowed to run. In fact, it has not been permitted to run for more
than 26 seconds. Despite the fact that in this situation, it would have
invoked wait_event_interruptible_timeout() with a three-jiffy timeout.
One thing to do is to modify the rcu_check_gp_kthread_starvation()
function to print the value of rsp->gp_kthread, then to also print
fields from the resulting pointer to task_struct to see what the thread
is up to. (It is tempting to suspect that this kthread might never have
been spawned, but in that case the grace period would not have started.)
For example, add the following in the "if (j - gpa > 2 * HZ)"
body:
if (rsp->gp_kthread)
sched_show_task(rsp->gp_kthread);
Don't forget to add the "{" "}" to accommodate the additional statement
within the "if" statement.
If the additional output shows that the rcu_preempt kthread is runnable,
the next question is "why is it not running?". If the output instead
shows that the task is blocked, the next question is "why didn't the
wait_event_interruptible_timeout() awaken it?
Thanx, Paul

rcu_check_gp_kthread_starvation --->end
It seems wait in rcu_gp_kthread. it should be no task blocked right?

Thanks for your answer during holiday.

And does the following diagnostic patch help? Its expected behavior
would be to turn a hard hang into something that recovered in a few
minutes, while giving a few stall-warning splats.

commit 7798a5efb2acabfa3ca788dd9b5b118eb1bff443

rcu: Awaken grace-period kthread when stalled
Recent kernels can fail to awaken the grace-period kthread for
quiescent-state forcing. This commit is a crude hack that does
a wakeup any time a stall is detected.

Sorry for late response because of holiday.
During my knowledge, now this issue is splitted to 2 issues.
First, there is a mistake in the kernel I used.
I used kernel is changed by someone else, and it ported a patch:
Author: Thomas Gleixner <tglx@linutronix.de>

+
It remove the "raise_softirq_irqoff" in tick_nohz_stop_sched_tick, so
the kernel will be not waked up in idle status.
Second:
The reason I thought linux-stable-rt has the same issue because of it
has a boot issue during systemd init:

I didn't know what's the problem here, so I thought it is caused by
the same issue.
Now with 1st issue resolved, I am digging the "mce hardware error".
Do you think this is a hardware issue?
Thank you very much for your help.
