Stress testing for perfromance is being done in preparation for the the Tencent PoC Sort Competition using the attached per scripts. The system either hangs, or the NVMe goes offline after 12 hours or so.

Hi,
We need to apply the following patch to the Ubuntu kernel to prevent
wrongly identification of ATARI partitions, as mentioned in the commit
log.
It still didn't make to Linus tree, but Jens Axboe already approved it
on linux-block.

block.git/commit/?h=for-4.8/core
