I have just applied these error-handling-related patches to kernel 
3.10.15 (without commenting out schedule_delayed_work(&dev->timer_work, 
HZ) yet) and checked the system again.

The full log is attached, the config is the same as I sent before.

Here are MEI-related messages from there:

---------------------------------------

No message flood anymore, which is good, but you are right, the problem 
seems to be somewhere deeper.

As far as kernel 3.11.6 is concerned, I see no message flood there but 
"wait hw ready failed. status = -110" is in the log, same as for 3.10.15.

Eugene
