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.
