Hi Tiwang,
I also got the same problem here.
*Mar 7 01:21:01.436: %CMRP-3-IDPROM_ACCESS: R0/0: cmand: Failed to access or process IDPROM 'power supply': No such file or directory -Traceback= 1#1322c15bbc01efab6530a3545ec1fac7 errmsg:E634000+2250 :10000000+2D628 :10000000+5D2AC :10000000+5AB40 evlib:EA03000+E328 evlib:EA03000+104D4 :10000000+52810 c:DDB4000+1E938 c:DDB4000+1EAE0
several minutes later the router shutting down itself.

* Fri Mar 7 01:23:12 UTC 2014: %SYS-0-RELOAD_MSG: (7627): Sleeping to allow drain before resetting
have you find a way to solve this case?
