    piix. hda, so I guess it is old-ide:

    piix 0000:00:1f.1: IDE controller (0x8086:0x27df rev 0x02)
    pci 0000:00:1f.1: PCI INT C -> GSI 16 (level, low) -> IRQ 16
    piix 0000:00:1f.1: IDE port disabled
    piix 0000:00:1f.1: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0x1810-0x1817
    Probing IDE interface ide0...
    hda: UJDA765 DVD/CDRW, ATAPI CD/DVD-ROM drive
    hda: host max PIO4 wanted PIO255(auto-tune) selected PIO4
    hda: UDMA/33 mode selected
    ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
    ide_generic: please use "probe_mask=0x3f" module parameter for probing
    all legacy ISA IDE ports
    ide-gd driver 1.18
    ide-cd driver 5.00
    ide-cd: hda: ATAPI 24X DVD-ROM CD-R/RW drive, 2048kB Cache
    Uniform CD-ROM driver Revision: 3.20

    If I try to access cdrom after undocking, I get:

    hda: status error: status=0x20 { DeviceFault }
    ide: failed opcode was: unknown
    hda: Strange, packet command initiated yet DRQ isn't asserted
    hda: status error: status=0x20 { DeviceFault }

    hda: Strange, packet command initiated yet DRQ isn't asserted
    hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }

    hda: drive not ready for command
    hda: status error: status=0x20 { DeviceFault }

    ...something similar scrolls when it hangs during s2ram, but it is too
    fast to read.

    Will try...
