Subject: OnStream DI30: undescriptive message: CoD != 0 in idescsi_pc_intr

OnStream Di30 (using ide-scsi and osst drivers), when reading
or writing I regularly get these kernel messages:

<3>ide-scsi: CoD != 0 in idescsi_pc_intr

Let's assume flaky hardware; nothing we can hold the kernel to
blame for (which is 2.6.19.1) -- it's a good thing it's calling
our attention. There's no data corruption, btw.

However, said message is quite useless because undescriptive
and too terse.

Not sure that this helps much.

Expand on a terse ide-scsi message.
Something is confused.
