ran out of input data - system halted.

[Gordon Stewart]

Dear List

Can any one tell me what causes the kernel to say:

ran out of input data - system halted.

I have my system in rescue mode and reading around i may have to install a new kernel.  Can any one advise me if this is the right thing to do or is there a simpler fix.  I do not want to reinstall the system if possible.

Thanks

Gordon Stewart
