tshoot status:
We have the same behavior on another slot.
Meanwhile, the LAG toward a core routers stays down for no reason.
The ASR is seeing an `old` partner MAC...

We have finally reloaded the chassis, with the card slotted.
On the reload, the card was discovered okay and the LAG that was previously down is now up and running.

We have taken traces to open the TAC.

We stop the maintenance until with have feedback from the support

We tried another card and it crashed again. Both cards were tested OKAY in LAB this morning.
We now suspects that the slot is messed up.

We are freeing another slot on the chassis to validate this.
We are still working isolated from the production

During the reload, we have removed all uplinks to the routers to work on it isolated.

We tried to insert the card back, the card is boot looping and crashed again the supervisor.
We will try another card after the next reload, and will open a TAC case anyway.

Ro-1.csd4 crashed during the OIR on the MPA.
The card has been slotted `powered down`, the crashed happened during the power up.

Impact might have been seen during the network convergence
