I see.

Be careful to put it correctly. The slot bracket has to be on the
side where the UART / USB / CAN connctors are. Do not insert the card
with the slot bracket pointing to the IDE connector.
Also be VERY carefully which card you insert. make sure it is
_really_ a 3.3V compatible card. [I fried a board by trying a Digitus
"DC SER2 Rev. 2.0 Serial PCI I/O Card" - this card has the key slots
for a 3.3/5V combi card, but the V_I/O pins are connected to the 5V
rail. The RAM chips didn't like to see 5V ...]

Can you attach a debugger? Or even try a post-mortem dump of the
logbif area? Both PCI and USB are working fine for me.

Maybe you can ask for a replacement. Your problems don't look normal
to me.
