ATA warnings in dmesg

ATA warnings in dmesg

[Aaron Gyes]

For the last few -mm releases (maybe longer, maybe it's in non-mm also)
my dmesg is full of this:

ata1: translated ATA stat/err 0xb0/00 to SCSI SK/ASC/ASCQ 0xb/47/00
ata1: translated ATA stat/err 0xb0/00 to SCSI SK/ASC/ASCQ 0xb/47/00
ata1: translated ATA stat/err 0xb0/00 to SCSI SK/ASC/ASCQ 0xb/47/00
ata1: translated ATA stat/err 0xb0/00 to SCSI SK/ASC/ASCQ 0xb/47/00

I've got a Western Digital Raptor 74GB, using sata-via on a K8T800 Pro.
Should I be scared?

I don't think you need to worry. Those messages are produced from the 
libata passthough code, whenever sense data has been requested...

0xb0 looks like a SMART command, so I would guess (haven't looked at 
-mm) that the ata ioctl handlers have been updated to request it.

Regards,
Jon.

That would make sense. I have a daemon running that requests the
temperature via SMART every minute or so. Even still, this fills up my
entire dmesg after not a very long time, can I turn these messages off
somehow? If not, can you point me to where in the code I could kill a
printk?

Sure, the printk is in drivers/scsi/libata-scsi.c, right at the end of 
ata_to_sense_error()..
