Hi.

  After updating kernel in -current machine, DVD-Drive in ATA
Secondary/Slave was not probed.

  If I back out sys/dev/ata/ata-lowlevel.c rev. 1.24, I could probe
it.

# atacontrol list
ATA channel 0:
    Master:  ad0 <IC35L040AVER07-0/ER4OA46A> ATA/ATAPI rev 5
    Slave:       no device present
ATA channel 1:
    Master:      no device present
    Slave:  acd0 <IDE DVD-ROM 16X/V3.10> ATA/ATAPI rev 0  <-- not probed
						          with latest kernel

  I hope to fix this problem before 5.2-RELEASE.

Cheers.
