Thanks! Sadly I'm not familiar at all with this logic, what should I
read up to be able to understand and investigate it more? When I'll
have time I'll look into it. For now, I'll read from
Documentation/scsi/*
Also I need to update kernel first because this here right now is
quite old one 4.6.2, maybe it's already fixed, but I've had seen this
since atleast 4.2
Here a bit different log, but still same issue.
