Dani:

Can you share complete "Driver logs" ( I mean /var/log/messages")

Also explain reproduction method. I will try to understand from logs what i=
s going wrong.

My very first observation is your "/dev/da24" is Xprot and it is just 20MB =
drive. So your application may be trying to write beyond max LBA of /dev/da=
24.
You should exclude /dev/da24 from your test.
