It is after I switched HDD mode in BIOS to "Serial ATA" (it was "Auto"
before)
Does it means that atacontrol list is not available for Serial ATA
native mode? (I don't think so, because I am using atacontrol on another
machines where disk are at AHCI mode AFAIK - Sun Fire X2100 M2 for
example)

The motherboard has 6x SATA ports, 2 are marked "for optical/removable
drives" and 4 are for HDDs.
System is booted from USB flash disk.
It is first time I see SATA devices attached as Master & Slave on same
ATA channel, previously (on different machines) it was always as Master
on separated channels. This configuration is worse if I want to utilize
all drives at the same time (in RAIDZ). One drive can achieve 110MB/s
read, both drives can achieve only 80MB/s each. ;(
Next strange thing is difference in Interrupts in systat output. With
mode "Auto', each ATA channel is listed on separated IRQ, with mode
"Serial ATA" channels are not listed but it seems that both are on the
same interrupt as bge0. Am I right? So it seems better to not use
"Serial ATA" mode settings.

Let me know if (and what) more details are needed.
