When I fire up 2.6.20 with an iq3124h I get:

ata1: SATA max UDMA/133 cmd 0xC8822200 ctl 0xC8822229 bmdma 0xC8822270
irq 25
ata2: SATA max UDMA/133 cmd 0xC8822400 ctl 0xC8822429 bmdma 0xC8822470
irq 25
ata3: SATA max UDMA/133 cmd 0xC8822600 ctl 0xC8822629 bmdma 0xC8822670
irq 25
ata4: SATA max UDMA/133 cmd 0xC8822800 ctl 0xC8822829 bmdma 0xC8822870
irq 25
scsi0 : sata_vsc
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
irq 25: nobody cared (try booting with the "irqpoll" option)
handlers:
[<c01796e0>] (vsc_sata_interrupt+0x0/0x194)
Disabling IRQ #25

I did a git bisect and came up with: [PATCH] libata: always use polling
IDENTIFY (800b399669ad495ad4361d134df87401ae36f44f)

I could probably cobble together a workaround to use irq-driven IDENTIFY
for this card but wanted to see if there was a better way.

Thanks,

Dan
