Some time ago I reported to Jonas privately that I had a problem with
my Quartz64 Model A and B and that I bisected it to this commit.
I just verified that the problem is still present in 2024.07, so I
guess it's time to report it to the (right) Mailing List.

The problem: packet loss, varying, but sometimes massive
Q64-A: The packet loss was usually between 8% and 30%
Q64-B: Packet loss up to 80% sometimes and this also resulted (then) in
its inability to receive a DHCP address.

https://lore.kernel.org/linux-rockchip/27139798.WhXITi6ROJ@bagend/
is where I brought this issue (also) up publicly, but that was on the 
linux-rockchip ML. The discussion that followed may provide some clues.

When looking up the mail I'm now replying too, I noticed a reply by
Stefan Agner with very similar symptoms, but on Odroid M1.

And the fix in my case has always been easy:

IOW: a (partial) revert of commit 25f56459aebc

It _could_ be that the issue is also present on the various SOQuartz
devices/boards, but I don't have those, so I can't check that.
But AFAIK they are rather similar to Q64-A and the change has also
been the same ... as was the case for Odroid-M1.

In case it's useful I have a log from the serial session with the
Q64-A (212.5 KiB) available.
Serial on Q64-B doesn't work, so I don't have that.

Cheers,
  Diederik
