Now I've updated kernel and the symptom is same with the previous that 
without set hw.ata.atapi_dma=0 I couldn't boot with the following 
message (written by hand):

acd0: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout
acd0: TIMEOUT - READ_BIG retrying (0 retries left)

The above msg looks a kind of loop and I'll try to do disk stresstest
for reproducing hangs I encountered.
