The user upgrade Ubuntu server to linux-image-4.10.0-26-generic_4.10.0-26.30_amd64.deb and it use a SSD of ES3000 V2 SSD which the correspond module driver of hio.ko is include in this kernel. The data write to disk seems was incorrect.
To format this sdd disk with xfs get error of "meta data corruption" and to use dd write data to this ssd disk and read out again, the sha256 chuksum is also mismatched.
It was tested for 4.8.0-34-generic, 4.10.0-26-generic and 4.12， this problem was not found on 4.8.0-34-generic, but both 4.10.0-26-generic and 4.12 have same issues.

Huawei reports that they get similar problem when upgrading from linux4.4 to linux4.8 and they fix it at the hio driver in 2.1.0.28 version as:
The modification for 4.8 is as below:
if (!test_bit(SSD_ONLINE, &dev->state)) {
ssd_bio_endio(bio, -ENODEV);
goto out;
}
#if (LINUX_VERSION_CODE >= KERNEL_VERSION(4,3,0))
blk_queue_split(q, &bio, q->bio_split);
#endif
