Thanks for pointing out that #249228 is a duplicate. The following suggestions have been made on other threads:
1) Set kernel parameter combined_mode=libata Doesn't seem to make any difference. 2) Set kernel parameter libata.dma=1. Not sure how to do this, but I created /etc/modprobe.d/libata-options and put options libata dma=1 in it. Now $ cat /sys/module/libata/parameters/dma 1 where it was 7 before. So it looks like the value has changed. Again, this doesn't seem to make any difference. Does anyone have any other suggestions?
