Subject: r8169 driver from kernel 5.0 crashing

Hi, after updating to kernel 5.0, the nic driver (r8169) has been
crashing whenever I start using heavy traffic on it (for example,
xferring large files to the box across my lan). The destination
harddrive may be sleeping and need to spin-up, or not, but the box
itself does not suspend/hibernate. The nic becomes completely
unresponsive and all connections to the box drop. After what I think
is several minutes, the connection comes back to life. The problem
happens consistently but seemingly not consistently at the same point.
For example, I can xfer a few 4gb files and it will crash at around
2-3gb on the first file. The next time it might not crash until 2-3gb
on the second file.Prior to kernel 5.0 I was using 4.19.12 and this
problem didn't occur. I have since downgraded back to 4.19.12 pending
what response this post gets.

Thanks for any help or assistance on how to proceed!

The nic is on-board ECS A75F-A:
