Hi all,

I've started using Jeff's libata patches from 
http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/, mostly so 
I can check the SMART status of a few drives that seem to be on their 
way out. I've only just noticed that recently, my kernel has been 
spewing out messages like the following every minute or so:

These messages don't seem to cause any trouble and I don't get any other 
errors. Is this just because of increased verbosity due to the patches? 
Can these messages be safely ignored / nuked?

I'm using 2.6.13-ck5 + 2.6.13-rc7-libata1.patch + 
reiser4-for-2.6.12-3.patch.gz + vesafb-tng-0.9-rc7-r1-2.6.13-rc6.patch. 
ata{1,2} are on a sata_sil controller, ata{3,4} are on sata_via.

It also has to be noted that I get similar errors when I try to 
enable/disable SMART automatic offline tests (and other similar 
settings) on a drive:

[4377001.595000] ata1: PIO error, drv_stat 0x51
[4377001.595000] ata1: translated ATA stat/err 0xb0/00 to SCSI

SK/ASC/ASCQ 0xb/47/00
[4377001.597000] ata1: status=0xb0 { Busy }

I'm getting similar messages when playing with SMART on another machine 
with vanilla 2.6.13.1 + 2.6.13-rc7-libata1.patch, but not the regular, 
minute-by-minute messages on that machine. This one has two drives on a 
sata_piix controller.

Other than that, no trouble. Thanks for the patches, they're really 
handy! :-)

PS: I'm willing to apply patches to, and reboot at will, the first 
machine, but not the second since it's my production web server.
