He guys!
while testing/stressing (dd'ing 200GB random to the drive) a brand new

Strictly speaking, this is not a kernel crash, it is just a failure to
write to the device and reporting an IO error and file system going
read-only as a result.
What does dmesg | grep ST8000 show?
If this 8TB is an SMR drive ('Archive'), be aware that under certain
circumstances, like for example unplugging/unpowering too fast after
massive random writes, this kind of IO failures are to be expected.

Hi Henk!
Thanks for clarification! Its indeed an Seagate Archive 8TB drive.
So it is vital info to let the drive settle down a bit when using it at
least in an HotPlug or USB szenario....
