router restart gone wrong !

Hi there,
I had a router c1841 cisco on which i upgraded the IOS and restarted the router. After restarting the router, it gave me the following messages (attached in code snippet) repeatedly upon attempting to restart. I had to use the tftpdnld method in ROMMON mode to bring the router back up. Can anyone help me with what exactly the reason might have been for these error messages ?
Possible software fault. Upon reccurence,  please collect
