8) If an uncorrectable error occurs during command queuing, the device sends to
the host the Set Device Bits FIS with the settings of ERR bit = 1, ERRReg =
ATAErrCode, I bit = 1, and SActive = 0 to report an error.
9) After reporting the error, the device accepts only the READ LOG EXT
command with page 10h specified and the reset requests (SoftReset and
COMRESET). The device reports abort for other commands.
10) If the device receives the READ LOG EXT command with page 10h
specified, queued commands are aborted. Then, after the device sends to the
host the Set Device Bits FIS (ERR = 0, ERRReg = 0, I = 0, and SActive
=0xFFFFFFFF), it sends to the host the log data for the READ LOG EXT
command with page 10h specified and reports the status of this command.
Next, the command queuing function is enabled, and commands can be
accepted again.
