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?

Thanks,
Richard
