This morning the ESP5 in one of our ASR1002 devices failed. Well, not entirely (I managed, for example, to update its firmware to 15.3(1r)S) but, if left enabled, goes through an infinite reset loop logging the lines below. It seems to have issues with the crypto hardware - is there any way to disable just that and maintain the rest of the card's functionality?
While at this, noob question: can an ASR1002 equipped with a SIP10 (equipped with a SPA-2X1GE-V2) work without an ESP? If it can, what would the performance penalty be? We are using these devices as PPPoE concentrators...
Many thanks in advance.

I just loaded a non-K9 IOS image, hoping that maybe the ASR would skip the crypto part when initializing the ESP - well, it didn't. A replacement ESP5 should arrive on site today, and I guess it's RMA time...
If the ESP stays continously in someother state than in the Active state from "show platform" output of the device, then the ESP needs to be replaced. Probably you could try to do a hard reseat before replacing it.
Another point is that any ASR1K device will not be able to forward any traffic without the presence of an ESP on it. It is the sole responsiblity of the ESP to take care of packet forwarding on any ASR1K device.

Well, it cycles endlessly through a sequence of states made of "booting", "init, ok", "active, ok", "disconnecting", "unknown" and then all over again, all these lasting for about three minutes and generating a core file. It was during "init, ok" and "active, ok" when I managed to update its firmware to 15.3(1r)S (and later on to 15.3(3r)S), but that didn't change anything.
Thanks for clearing up the part about the ASR1K working without an ESP.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to
login w/ SSH 1 or 2 to the device compare to IOS device. After
investigation, the there is 1s delay between the client KEXDH_INIT and
the server (XR) KEXDH_REPLY. After debug ssh serv...
