RT throttling and mmc hardware interrupt timeout

Hi all:
Recently, I do test with btrfs filesystem on emmc. When I see the message "sched: RT throttling activated", uart, network and other peripherals are not responding.
But, the timer is ok, so I can see the following messages:
"mmc0: Timeout waiting for hardware interrupt." again and again. Finally, "I/O error" messages are coming and the btrfs filesystem crashes.

I think, because I use threadirqs, so most irqs are processed in threads, yes, RT threads. When "sched: RT throttling activated" comes out, RT threads can not be execute for some time, so, we can see mmc interrupt timeout message.

My kernel version is 3.10.55, I know that's very old. Still, I want to know, is there any patch for this problem? Or does any one encounter the same problem? Thank you.
