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.
