If I had in ata_host_intr someting like [1] for checking the altstatus, my ATAPI drive works. It report "ata_altstatus take 3us", for driver that wasn't worked before.
I don't know if it is a correct fix and where it should be putted (in libata-core or in the pata_via check_altstatus callback). I don't know if it should be used only for ATA_CMD_SET_FEATURES && SETFEATURES_XFER.
Now real testing could begging.

[1] for (i=0; ata_altstatus(ap) & ATA_BUSY; i++) { if (i > 10) goto idle_irq; udelay(1); } if (i) printk("ata_altstatus take %dus\n", i);
