ATAng: ata1-slave CDRW is only sometimes detected

Hello,

I have the following units on a MSI KT4V (KT400/VT8235) motherboard
(80pin cable is used for both primary and secondary controller):

  ata0-master:	WDC WD800JB ATA-6 disk
  ata0-slave:	
  ata1-master:	TEAC DV-516E DVDROM drive
  ata1-slave:	TEAC CD-W524E CDRW drive

For about a week I have the aforementioned setup.  I had the same setup
before ATAng got committed, but with a different DVDROM drive, without
problems.  When ATAng got committed I had only the CDRW drive as
ata1-master, also, without problems.


Most of the time the CDRW drive is not detected and I get:

Sometimes the CDRW drive is detected and I get:
