--- Comment #126 from Eric Benoit (eric@...s.ca) ---
FWIW I believe this issue is affecting ZFS as well. I'm getting the occasional
checksum error on a random drive of a RAID-Z configuration (five 4T WD Reds). 

I'd initially suspected a chipset (Intel 5400) issue as it's spread more or
less evenly across the devices. However it's definitely a software issue, as it
only occurs running kernel 4.19.[26] and disappears entirely with 4.18.20.

On a different workstation with ZFS and Seagate drives I haven't been able to
reproduce the issue.
