ata_piix hang in 2.6.13-rc5

ata_piix hang in 2.6.13-rc5

[Jesse Barnes]

I recently tried to upgrade an ICH5 based box I have to see if a PCI 
resource allocation bug went away, but was stymied by the fact that 
recent kernels (2.6.12 from Fedora and 2.6.13-rc5) hang when ata_piix 
probes for drives.  The last messages I get are these:

Loading ata_piix.ko module
ACPI: PCI Interrupt 0000:00:1f.2[A] -> GSI 18 (level, low) -> IRQ 177
ata1: SATA max UDMA/133 cmd 0xC800 ctl 0xC482 bmdma 0xC000 irq 177
ata2: SATA max UDMA/133 cmd 0xC400 ctl 0xC082 bmdma 0xC008 irq 177
ata1: SATA port has no device.
scsi0: ata_piix
ata2: dev 0 ata, max UDMA/133, 312581808 sectors, lba48
<hang>

Is this a known problem?  Is there anything in particular I should try?

Thanks,
Jesse

For what its worth, I'm seeing the same thing on a 2.6.13-rc5 machine
with sata_nv on an x86_64 machine. I can get around it by using noapic.
I initially assumed it was some ACPI or IRQ issue, but my box hangs at
the exact same place, right after announcing the first device.

Try booting with noapic.

Thanks a lot, noapic worked.  I guess that means this is a generic IRQ 
routing or setup issue, rather than something SATA specific?
