Event logs when a reboot is done

Usually when I reboot an AP this is the reading I get in the event logs.

00:00:00 UT : 01/01/01 : File C:/ISIPPC/pssppc.250/bsps/devices/whisp/syslog.c : Line 918 System Reset Exception – External Hard Reset
00:00:00 UT : 01/01/01 : File root.c : Line 940 System Startup


However when i reboot 1 of my APs the following registers in the event log.

12:15:00 UT : 03/24/06 : File C:/ISIPPC/pssppc.250/bsps/devices/whisp/syslog.c : Line 918 System Reset Exception – External Hard Reset WatchDog Cur ExtInt 75 Max ExtInt 593 Cur DecInt 27 Max DecInt 33 Cur Sync 0 Max Sync 27 Cur LED 0 Max LED 1 Cur EthXcvr 0 Max EthXcvr 1 Cur FEC 11 Max FEC 259 Cur FPGA 26 Max FPGA 209 Cur FrmLoc 37 Max FrmLoc 133 AAState 0
12:15:00 UT : 03/24/06 : File root.c : Line 940 System Startup

Can anyone tell me what this means?

The second event appears after external reset, for example after a power fail.
