Recently, i encounter aplay failed on arm 64 bits core.

I wasn't aware that ALSA's mmap code had been ported to ARM64.

[ 87.403146] 823 (aplay) Bad mode in Error handler detected, code 0xbf000000 [ 87.573201] 823 (aplay) Bad mode in Synchronous Abort handler detected, code 0x86000007 [ 87.743126] 823 (aplay) Internal error: Oops - bad mode: 0 [#1] PREEMPT

What does "bad mode" mean? Is this a real CPU? Does it behave correctly?
