In the command completion code we need to check for abnormal completion due to underflow, but ignore it when it occurs in some commands, like inquiry. This is why we check for rw command - it is equivalent to !inquiry.
I'll see if we can change the check to explicitly ignore certain commands which complete abnormally with underflow.
What about 32-byte CDs or things like Write Same?
You're talking about VARIABLE_LENGTH_CMD (opcode 0x7f) for 32-byte CDs, right?
I need to check on WRITE SAME.
