If reproduce again, please take also the content of
"LRU_list_mutex" and "flush_list_mutex" and "page_hash_latch".

They contain the owner ID of the thread. It will help analysis much.

Yasufumi,

It does not seem hardware bug, I have no problem with standard Innodb.

Also why you think it is related to page_hash. As you see show innodb
status also hang, there is mutex srv_monitor_mutex affected. It seems
sync_array is in problem place.

Vadim,

The standard Innodb doesn't use instructions of atomic operation hardly.
And the other mutex may be only affected by the hungup of the x-lock waiting.

Because percona-patches don't use "page_hash_latch" yet (uses page_hash_mutex)

I have never experienced such hungup of our tpc-c workload up to over 16 CPU (x86_64).
