2911 Router crashes after i set the ATM interface

Question:

We bought a cisoc WS-C3560V2-48TS-S Price 2911 Router with an EHWIC-VA-DSL-A Card. I did the Dialer Setup without any problem but if i set the ATM interface with the commands:

pvc 8/35

  pppoe-client dial-pool-number 1

The Router crashes after some seconds. I didn't connceted the phone line to the DSL card.

Does you guys have any clue ?

Thanks in advance patrick

The DSL setup:

controller VDSL 0/0/0

interface ATM0/0/0

no ip address

no atm ilmi-keepalive

!

interface Ethernet0/0/0

no ip address

shutdown

!

interface Dialer1

ip address negotiated

ip mtu 1492

ip nat outside

ip virtual-reassembly in

encapsulation ppp

shutdown

dialer pool 1

dialer-group 1

ppp authentication chap callin

ppp chap hostname xxx@xxx.ch

ppp chap password 7 xxxxxx

And here the relevant part of the crash file:

Answer:

While I have not yet been dealing with this issue before, based on the output I assume that the most probable cause of this problem is either an IOS bug or a faulty RAM module - hopefully, it's the IOS. Can you perhaps try moving to a different IOS version,WS-C3560V2-48TS-S either downgrading to 15.1(4)M2 or upgrading to 15.2(4)M2?
