Hello Mr. Garzik:

We have a removable, ATAPI, SATA device and we are having the following
problem with Linux (kernel version 2.6.15.6). The device recieves a MODE
SENSE command. After receiving this command, it is supposed to receive a
12-byte packet command, which it recieves. Afterwards there is supposed
to be an IRQ, and then the data is read from the device. However, in one
computer we have with a VIA chipset, the device keeps getting zeroes
without stopping. In other words, it gets the 12-bytes and the continues
to recive bytes all of which are zero. The device never gets the IRQ,
therefore it does not respond.

Any ideas on this?

Thanks in advance for any help.

Attached are some kernel messeges. I ran dmesg several times and
appended the output to the attached file, so there may be some
redudancy. However some of the commands or debug lines do appear to
repeat themselves. As you requested, I changed "#undef ATA_DEBUG" to
"#define ATA_DEBUG".

As far as the device is concerned, is an unreleased product of the
company I work for. That's why I did not give a name, because we don't
have an official name yet. But like I said, it is SATA, removalbe ATAPI.
If you want/need more information let me know.

Dario

Oops.

Yes, we have tried other controllers, mainly Intel and nvidia. No
problems with either one. Only the motherboard with the VIA controller
gives the problem.
