Hi,
I found the related code in the function sym_int_sir:
/*
* The device wants us to tranfer more data than
* expected or in the wrong direction.
* The number of extra bytes is in scratcha.
* It is a data overrun condition.
*/
case *SIR_DATA_OVERRUN*:
if (cp) {
OUTONB (HF_PRT, HF_EXT_ERR);
* cp->xerr_status |= XE_EXTRA_DATA;*
cp->extra_bytes += INL (nc_scratcha);
}
goto out;
I'm not familiar with SCSI.
What does DATA_OVERRUN actually mean?
How can it be triggered?
Could you give more details about it?
Thanks for your help.
