aic7xxx: DV failed to configure device

I'm testing an Adaptec SCSI controller + an IBM drive. All the things used to be fine before I had made the low-level format of the drive (thru the Ctrl-A Adaptec's menu). And now after

modprobe aic7xxx

I have:

scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36

The message

scsi0:A:0:0: DV failed to configure device. Please file a bug report against this driver.

had never appeared before the low-level format. But it seems that after the format the drive still works fine.

So, what does this message mean? And can I just ignore it?

Some additional info: it's the PCI64 card installed in a 32-bit PCI slot, Domain Validation is turned on thru the Adaptec BIOS setup.

Thanks in advance.

you failed to mention which exact kernel you were using... (that matters since the aic7xxx driver changes a lot over time, and especially it changed recently in this area a lot)

Yes, I'm sorry. 2.6.10.

That particular code was completely changed for 2.6.12-rc5; could you see what that kernel makes of this, please?

Thanks,

James

Ok, 2.6.12-rc5:

It seems that things are in order, do I understand right? So, why and how the low-level format affects the old driver's behaviour?

Thanks in advance.

I can't answer that ... part of the reason for ditching the in-driver aic7xxx DV is that it was where an astonishing number of bugs kept turning up.
