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
