"FPGA Critical Error" on Cisco Router

[Dlaport]

HI

I was wondering if anyone had more information on this error that i have been seeing on a few 1941 ISR's:

%EHWIC_CELL_MSG-1-FPGA_CRITICAL_ERROR: FPGA Critical Error: EHWIC GDF to KWD Read Timeout Err Event, HWIC slot 0 

•  Does it indicate a dying Router, a dying 4G module or both?
• Is there anyway to recover for it?

Thanks in advance
