Maybe there are some tunings available to select PIO4 (most cf are using it)? In 8-STABLE there were added tunables hint.ata.X.devX.mode and hint.ata.X.mode to set ATA mode during boot. Before that - only hw.ata.ata_dma. > P.S. I have two verbose dmesg but they are rather big. If needed i can post them hear. Verbose dmesg could be useful in many cases. Better upload it somewhere else and post a link here. -- Alexander Motin
