7i77 lost connection while encoder counts (PREEMPT-RT)

Category: Driver Boards

pin hm2_5i25.0.write.time did not change anymore.

Suggests this is a PCIE communication issue and probably
not related to 7I77 5V

It may indicate a grounding/EMI issue. Do you have an issue when
the 7I77 in not connected to the rest of the machine?

This is why i asked for a dmesg log as PCIE issues should show up there.
