Below are results of my tests with patch from Takashi (and MSI enabled). 

Using arecord everytime ends in freezing machine. My laptop freezes exactly 
when recording stops working. My test procedure looks like this:

1) on one console run arecord and see the output (You should see some garbage)
2) on another console run cat /etc/*
3) wait for freeze ;)

Here is section from /var/log/messages (text in <> can be seen only on 
console, syslog doesn't catch to save it to disk, and machine freezes):
