I get this problem when I boot my 2611XM. Evan setting confreg to
Unexpected exception to CPUvector 1100, PC = 0

Any help appreciated, Ned
Tracebacks are caused by IOS bugs - you should upgrade the IOS and if problem peresists open a case with the Cisco TAC.
True.
If it is not booting maybe it is a hardware problem. "PC = 0 seems a bit suspicious."
Try booting with all network interfaces removed, if you have any non-integral modules. WICs or NMs. Unplug network cables too.
Have you got enough memory for the IOS? Maybe with far too little memory it would just crash?
Also if that does not help:- If the router is a toy, take the lid off and gently re-seat any socketed components (or get someone who knows what to do to do it) by pressing on them making sure the board is supported behind and that anti-static precautions are taken.
If it is for business open a TAC case and get it fixed.
Maybe the image is corrupt? Checksum 0xbebe seems a bit repetitive? I checked, the checksum is correct so the image is likely, but not necessarily OK.
Maybe the developer fixed the checksum:)
