    I have a machine running 5.3. It is a compaq dl380. It has
    ida0: <Compaq Integrated Array controller> as the controller
    for the disk.

    It has hung a couple of times in the last week in 'getblk'.
    When I try to panic it, I get 'ida_command: out of QCBs' (as below).

    I'm not exactly sure what the 'QCB' is, a control block for the
    scsi controller of some sort. Can these be tuned up? could there
    be a leak?

    ida0: <Compaq Integrated Array controller> port 0x2000-0x20ff mem
    0xc4000000-0xc4ffffff,0xc5000000-0xc5ffffff irq 10 at device 1.0 on pci0
    ida0: [GIANT-LOCKED]
    ida0: drives=2 firm_rev=1.42
    idad0: <Compaq Logical Drive> on ida0
    idad0: 12498MB (25597920 sectors), blocksize=512
    idad1: <Compaq Logical Drive> on ida0
    idad1: 115180MB (235889280 sectors), blocksize=512
