Thanks Geert for the help. Although I already posted a revert, I'm still 
trying to root-cause this issue. Do you perhaps know whether sata_rcar 
controllers support NCQ and if so, what queue depth these controllers 
support? I think that information is available in sysfs. Here is an 
example for a VM:

# (cd /sys/class/scsi_device && for a in */device/*/*/ncq_prio_enable; 
do p=${a%/ncq_prio_enable}; grep -qi ata $p/inquiry || continue; grep 
-aH . $p/{queue_depth,ncq*}; done)
2:0:0:0/device/driver/2:0:0:0/queue_depth:32
2:0:0:0/device/driver/2:0:0:0/ncq_prio_enable:0
2:0:0:0/device/driver/2:0:0:0/ncq_prio_supported:0
2:0:0:0/device/generic/device/queue_depth:32
2:0:0:0/device/generic/device/ncq_prio_enable:0
2:0:0:0/device/generic/device/ncq_prio_supported:0
6:0:0:1/device/driver/2:0:0:0/queue_depth:32
6:0:0:1/device/driver/2:0:0:0/ncq_prio_enable:0
6:0:0:1/device/driver/2:0:0:0/ncq_prio_supported:0

Thanks,

Bart.
