SATA ATAPI AHCI error messages?

SATA ATAPI AHCI error messages?

[Gaston, Jason D]

Hello,

We are seeing the following error messages in dmesg with the 2.6.16-rc5
kernel.  I have also tried to apply the git10 patch and still see the
same errors.  This is seen using a Plextor PX-716SA or PX-712SA SATA
DVDRW drive when in AHCI mode.  I do not see this message when the SATA
controller is set to IDE mode, in the BIOS.  I have reproduced this
using Intel ICH6R, ICH7R and ICH8 SATA controllers.  I have
atapi_enabled=1 set in the libata-core.c file.  These error messages
continue to be repeatedly logged about every 2 seconds.  Can someone
tell me what is going on and if this will be addressed in the next RC
release of the 2.6.16 kernel?

Probably its just too chatty, since ATAPI throws a lot of errors...

Does ths still occur if you boot to a command line and don't have all
the gnome/kde crap running and polling your drive ?

TUR should not be getting aborted command replies off a CD. Most odd

It's been a while, and my memory of such is fuzzy,
but I think I have commonly seen ATAPI drives (in the past)
that simply fail TUR as above when the drive is open
or media is not present (one of those two, forgot which).

Cheers

I have media in the drive and still see the error.  We are seeing the
errors when the system is booting, before gnome or KDE is loaded.

Yes, I have seen that also.  I posted a patch to rate-limit the
printk's but it wasn't accepted since they are mostly there for
debugging anyway.... or so it seems.

I double checked and found that the messages do stop when media is
inserted into the drive.  They pick up again as soon as the media is
removed.

Is there any way we can get this fixed?

Thanks,
