Do you have another PCIe card to try on the same reboot test on this board?

I've seen this on at least two Mellanox cards.  I'm running similar tests
on a different type of card now.

FWIW, reboot tests on two machines with Mellanox cards failed, while the
same test on a machine with a different proprietary card succeeded.

Thanks, Bjorn.

I don't have the same Mellanox card as yours, but I will also run
similar reboot test to see if I hit the same issue with my card.

Any more hints on this?  Nothing has changed on my end, so of course
I'm still seeing this, always on machines with Mellanox, and never on
other machines.  Could this be a hardware issue like a signal
integrity or margin issue?  I don't know where to go from here because
I'm not a hardware person, and I don't know anything to do in
software.
