    Date
    IBM R30 Laptop, ALI15X3 IDE onboard chip, internal IDE harddisk & CDROM gives
    irq 15: nobody cared!
    ....
    Disabling IRQ #15

    Message repeats ~ 1/min.

    00:10.0 IDE interface: ALi Corporation M5229 IDE (rev c3) (prog-if fa)
    Subsystem: IBM: Unknown device 050f
    Flags: bus master, medium devsel, latency 32, IRQ 15
    I/O ports at 7050 [size=16]
    Capabilities: [60] Power Management version 2

    Any ideas ?
