Stock 4.2-RELEASE. Two IDE controllers on motherboard. One
Tertiary IDE controller installed in bus slot with 8MB IDE hard
drive attached.
>Description:
As the ata driver is the next generation, I tried it first. I
could not get it to attach my tertiary IDE controller. Flipping back
to the wd driver revealed that it supports it just as well as
3.4-RELEASE did.
In 4.2 (with ATA), I have these kernel lines:
device ata0 at isa? port IO_WD1 irq 14 flags 0xa0ffa0ff
device ata1 at isa? port IO_WD2 irq 15 flags 0xa0ffa0ff
device ata2 at isa? port 0x1e8 irq 11 flags 0xa0ffa0ff
device ata
device atadisk # ATA disk drives
device atapicd # ATAPI CDROM drives
#options ATA_ENABLE_ATAPI_DMA # Enable DMA on ATAPI devices
and I get these boot-ups probes related to my IDE controllers and disks:
atapci0: <Intel PIIX3 ATA controller> port 0xe800-0xe80f at device 7.1 on
pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
...
ata4 at port 0x1e8-0x1ef,0x3ee irq 11 flags 0xa0ffa0ff on isa0
ata4-master: ata_command: timeout waiting for intr
ata4-master: identify failed

ad2: 8063MB <IBM-DHEA-38451> [16383/16/63] at ata1-master WDMA2
acd0: DVD-ROM <Pioneer DVD-ROM ATAPIModel DVD-114 0125> at ata1-slave using
\
PIO4
you can see that the 3 hard drives and the IDE CD-ROM on the first two IDE
controllers probe fine, but we're missing the tertiary IDE controller and
the fourth hard drive.
However, with these WD kernel lines:
device wdc0 at isa? port "IO_WD1" irq 14 flags 0xa0ffa0ff
device wd0 at wdc0 drive 0
device wd1 at wdc0 drive 1
device wdc1 at isa? port "IO_WD2" irq 15 flags 0xa0ffa0ff
device wd2 at wdc1 drive 0
device wd3 at wdc1 drive 1
device wdc2 at isa? port "0x1e8" irq 11 flags 0xa0ffa0ff
device wd4 at wdc2 drive 0
device wcd0 #IDE CD-ROM
all 4 disks and the IDE CD-ROM work just fine (Notice the wdc2 (tertiary
IDE controller) and wd4 (5th IDE disk hanging off tertiary IDE) probes:
ide_pci0: <Intel PIIX3 Bus-master IDE controller> port 0xe800-0xe80f at
device 7.1 on pci0
ide_pci0: driver is using old-style compatability shims

>How-To-Repeat:
Install a tertiary IDE controller on port 0x1e8, and use the two
sections of kernel configs above to confirm that it works with the wdc
driver but no the ata driver.
>Fix:
Not known. Work-around: use the wdc driver for now.
