What is the model of the switch and what IOS version are you using?

[cvf-reg2cis]

Model WS-C6509-E

Version 12.2(33)SXJ1

Are you seeing the switch crashes again and again to Rommon?

The first message on syslog indicates a parrity error(indicative of hardware issue). So if it is not able to boot prompty, please replace it.

Hope this helps. Please do remember to rate all useful posts.

Thanks,

Madhu
