ISDN dsl errors

My c876 router logs the following errors:

*Apr 14 10:24:46.943: esw_dtc_ltc4258_reg_write: no acknowlege from POE

*Apr 14 10:24:46.943: esw_mrvl_pdc_hardware_config failed on slot 0/0

*Apr 14 10:24:48.451: esw_dtc_ltc4258_reg_write: no acknowlege from POE

*Apr 14 10:24:48.451: esw_mrvl_pdc_hardware_config failed on slot 0/0

Slot 0/0 contains an ATM interface with adsl module. The ATM module is configured like this:

interface ATM0

no ip address

ip verify unicast reverse-path

no ip redirects

no ip unreachables

no ip route-cache cef

no ip route-cache

no atm ilmi-keepalive

pvc 0 8/48

encapsulation aal5mux ppp dialer

dialer pool-member 1


dsl operating-mode auto

The ATM interface also keeps restarting every few hours.

Is my hardware failing or is there some other solution?
