A)

atapci1: <Intel ICH8 SATA300 controller>
atapci2: <Intel ICH8 SATA300 controller>
ad8: 29314MB <IBM DTLA-307030 TX4OA60A> at ata4-master UDMA100
acd0: DVDR <PLEXTOR DVDR PX-760A/1.03> at ata4-slave UDMA66
ad10: 476940MB <WDC WD5000YS-01MPB0 07.02E07> at ata5-master SATA150
SMP: AP CPU #1 Launched!
Trying to mount root from ufs:/dev/ad8s2a

104]  atacontrol info ata5
Master: ad10 <WDC WD5000YS-01MPB0/07.02E07> Serial ATA II
Slave:       no device present
106]  atacontrol mode ad10
current mode = SATA150
107]  atacontrol mode ad10 sata300
current mode = SATA150

108]  man atacontrol
        Currently supported modes are: PIO0, PIO1, PIO2, PIO3, PIO4,
        WDMA2, UDMA2 (alias UDMA33), UDMA4 (alias UDMA66), UDMA5 (alias
        UDMA100) and UDMA6 (alias UDMA133).
No SATA modes shown.
SATA300 not supported.

B)

BIOS: ICH8 full enabled: SATA1 .. 6: First disk SATA1 is /dev/ad10
      ICH8 compatible  : SATA1 .. 4: First disk SATA1 is /dev/ad0
Experimental/test disk on JMicron363 is always /dev/ad8.

C)

A kernel with atapicam hangs.

 A)
 
 BIOS: ICH8 mode change IDE -> AHCI:
 This enables ata (atacontrol) mode SATA300.

 Would be optimal:
 ICH8:
 SATA1: ad0
 SATA2: ad1
 SATA3: ad2
 SATA4: ad3
 SATA5: ad4 (enhanced mode only)
 SATA6: ad5 (enhanced mode only)
 JMicron:
 SATA7: ad6
 SATA8: ad7
 PATA1: ad8
 PATA2: ad9
 
 But with enhanced mode ad0 changes to ad10 - and so on.
 Where are then ad0, ad1, ...?
State-Changed-From-To: open->closed 
State-Changed-By: mav 
State-Changed-When: Sat Nov 7 19:07:43 UTC 2009 
State-Changed-Why:  
a) sata connection speed detected automatically. Current driver doesn't 
control it. 
b) two drive slots reserved for every ata channel.
