The reasons for IRQ timeouts can be many and most times, archaic
and difficult to trace, if they are not intermittent.

If _could_ mean that at that time (since you report it happens once
or twice a month) the computer was under heavy I/O bounded load and
you tried to tell the disk to go do yet something else different. An irq
got lost, and the disk had to be reset to a known state before continuing.

It _could_ mean that your disk (which I assume is not a new one) is
having problems coping with its spindle timeout. That's the time the
disk will wait before shutting down its motor. If a command comes
in between the spin-up and the ok, it could get lost.

Again, without more data, this is difficult to track down, but these are
two possible explanations AFAIK.
