logical block out of range

[Brandin L Claar <claar@arl.psu.edu>]

I just found the following error in my log after doing a "dd if=/dev/rsd0c 
of=/dev/null".  I am running a kernel compiled out of current.

Jan 23 15:38:38 dejavu /bsd: sd0(ncr0:0:0): Check Condition on opcode 28
Jan 23 15:38:38 dejavu /bsd:     SENSE KEY: Illegal Request
Jan 23 15:38:38 dejavu /bsd:      ASC/ASCQ: Logical Block Address Out of Range
Jan 23 15:38:38 dejavu /bsd:          SKSV: Error in CDB, Offset 2

This is my disk/controller info:

ncr0 at pci0 dev 13 function 0 "Symbios Logic 53c875" rev 0x26: ultra wide 
	scsi, irq 11
scsibus0 at ncr0: 16 targets
sd0 at scsibus0 targ 0 lun 0: <IBM, DNES-309170W, SA30> SCSI3 0/direct fixed
sd0(ncr0:0:0): WIDE SCSI (16 bit) enabled
sd0(ncr0:0:0): 40.0 MB/s (50 ns, offset 16)
sd0: 8748MB, 11474 cyl, 5 head, 312 sec, 512 bytes/sec, 17916240 sec total

The filesystems seem okay.  I imagine the error is probably just a result
of me abusing the raw disk device with dd.  I suppose it could just be a
result of trying to address past the end of the logical disk, but I wasn't
sure if it was supposed to be handled in this way or not.  Actually, I am
being a bit paranoid because this machine was previously running linux 
and had reported some SCSI errors at that time as well.  Anyhow, I wanted 
to see if anybody else had any thoughts.  Thanks.
