[Vasiliy Tolstov]

Hi! I have stable problems with all Samsung SSD drivers like PM863 and
EVO 850 Pro.

Time after time scsi bus reset link with messages:

I'm try to remove drive and add it again message not appears may be
one hour or more. I'm try different servers from HP and Supermicro and
error is present. Also i'm try various disk from this series and
nothing changed.

If i have massive workload like writing to ext4 fs on this ssd drivers
i get corrupted ext4 journal and readonly fs.

My kernel version is 4.4.34
May be some Samsung engineers presented in this mailing list and ca
help to solve this errors? Or for server i need only Intel SSD (yes if
i use intel ssd this error not happening, this is not intel
advertising)
