ata1:slave is not recognized

[Dmitry Morozovsky]

Dear colleagues,

one of my machines fails to recognize 4th device at ata bus:

root at muzzy:~# atacontrol list
ATA channel 0:
    Master:  ad0 <WDC WD800BB-00CAA1/17.07W17> ATA/ATAPI rev 5
    Slave:   ad1 <IBM-DTLA-307015/TX2OA60A> ATA/ATAPI rev 5
ATA channel 1:
    Master: acd0 <CD-W540E/1.0D> ATA/ATAPI rev 5
    Slave:       no device present

(ata1:slave is actually SONY DVD Drive, and is successfully recognized under
Wind0ze2k). hw.ata.atapi_dma setting is not relevant. Both 4.8-R and
5.1-R miss this device.

atacontrol detach/attach 1, as well as atacontrol rescan 1, does not change
device list.

dmesg excerpt for verbose 4.8-R boot is below.

Any comments? Should I file a PR?


Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]
