Actually this causes a hang like:

hda: TEAC DW-552G, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: ATAPI 52X DVD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.20
Red Hat/Adaptec aacraid driver (1.1.2-lk2 Nov 11 2005)
3ware Storage Controller device driver for Linux v1.26.02.001.
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 7
PCI: setting IRQ 7 as level-triggered
ACPI: PCI Interrupt 0000:00:1f.2[B] -> Link [LNKD] -> GSI 7 (level, low)
-> IRQ

ata1: SATA max UDMA/133 cmd 0x70C8 ctl 0x70E6 bmdma 0x70A0 irq 7
ata2: SATA max UDMA/133 cmd 0x70C0 ctl 0x70E2 bmdma 0x70A8 irq 7

ata1: dev 1 ATA, max UDMA/133, 234441648 sectors: lba48


All processors are in idle_loop in xen.
