Hello Matthew,

And.. have some more probs (was a little bit too fast), perhaps you have
an idea:
When I dd more than 556k bytes to the drive, I get errors.
I have attached a log, some ideas would be great.

If you sent the patch, it might help people have ideas about what might
be wrong with it.

Attached.
But "special" ugly hack, far away from final code.
I have only changed scsi_scan.c, but nothing else (only printk to track the extecution, perhaps I should read a howto for kernel debugging...)

The problem, I think must have someting todo with:
cpqfcTSworker.c from linux-2.4.20:
---snip---
          if( (Exchanges->fcExchange[ ExchangeID].type == BLS_ABTS)

                  &&
            // Second, does the source of this ACC match the destination
            // of who we originally sent it to?
             ((Exchanges->fcExchange[ ExchangeID].fchs.d_id & 0xFFFFFF) ==
             (fchs->s_id & 0xFFFFFF)) )
          {
            // YES! NOTE: There is a bug in CPQ's RA-4000 box
            // where the "reason code" isn't returned in the payload
            // For now, simply presume the reject is because the target
            // already completed the exchange...

//            printk("complete x_ID %Xh on ABTS RJT\n", ExchangeID);
            cpqfcTSCompleteExchange( cpqfcHBAdata->PciDev, fcChip, ExchangeID );
          }
---snap---

I have tracked down the prob till now to:
scsi_lib.c ->scsi_softirq_done

Will go on tomorrow.

cya,
	Ingo
