Re: rcu_sched self-detected stall on CPU

[Rumen Telbizov <telbizov@gmail.com>]

I do see the stalls and kernel messages all at the same time across all nodes indeed!
I'll try to not use the server as a client and see if it makes any difference.

If anyone has any other pointers - please let me know.

Thank you,

I'm not sure, but I seem to remember that this used to have the
potential for deadlock.
