Periodic, apparently harmless, scsi error?

[Ben Pfaff]

Using aic7xxx driver in 2.2.15pre16 on a PCI 2940UW, with 3
Micropolis 4.3 GB UW internal HDDs and a Sony DDS-3 external tape
drive, I occasionally get a message logged of this form:

    scsi : aborting command due to timeout : pid 14033109, scsi0,
    channel 0, id 1, lun 0 Read (10) 00 00 2d 09 8f 00 00 70 00

These happen maybe once a day or so, on an apparently random one
of the 3 HDDs (ids 0-2).  They're apparently harmless, since
everything still works.  I also get one of these at boot time.

Is there something that I should be worried about here?  Or is
there a way I can keep this error from recurring?

(This error didn't occur in 2.2.9, my previous kernel, IIRC.)

Thanks,

Ben.
